                                                                 Preface



        Introduction

              With VAX Public Access Communications (VAX PAC), you
              can use your computer system to communicate with other
              computer systems. The system with which you communicate
              is called the remote system. Your system uses one or more
              modems to communicate with a remote system over phone
              lines.

              You can, for example, use VAX PAC to get timely business
              information from such sources as Dow Jones News/Retrieval
              Service, The SOURCE, or CompuServe. Or, you may want to
              communicate with one of your own remote branch offices.
              In this case, you can use VAX PAC to do work on the
              remote system from the system in your office, or to
              transfer files back and forth. You can communicate with
              any remote system to which you have access that has the
              industry-standard asynchronous RS-232C, RS-422, or RS-423
              interfaces.

              VAX PAC is not, however, a communications network.
              If there are several computers at one site, Digital
              recommends you use a DECnet system.

        Intended Audience

              This manual is intended for system managers and those
              responsible for setting up and maintaining systems that
              communicate with remote databases. Some knowledge of VMS
              or A-to-Z systems is helpful.

                                                 Installation Procedures



              This chapter contains installation and postinstallation
              requirements; information on installation procedures for
              VMS and A-to-Z systems; and information on modem use,
              installation, and testing.

        1.1 VAX PAC Installation Overview

              VAX PAC installation consists of the following steps:

                 o  Define standard connections; refer to Section 2.4.3.



        1.2 VAX PAC Installation Requirements

              It takes approximately 10 to 20 minutes to install the
              VAX PAC software. The time varies depending on the
              distribution medium and the system on which you are
              installing VAX PAC.

              To install VAX PAC, you need the following:

              o  Any VAX CPU or VAXcluster environment running VMS
                 Version 5.4 or higher

              o  The Product Authorization Key (PAK) for VAX PAC
                 installed and loaded

              o  Sufficient disk space

              o  Distribution media: either one TK50 tape cartridge or
                 one 9-track 1600 bpi magnetic tape

              o  A modem connected to a phone line

              o  Modem cables

              o  The VAX PAC installation kit, which includes the
                 distribution media, the documentation, and the
                 VT200/VT300 keystrip

        1.2.1 Product Authorization Key (PAK)

              This product supports the License Management Facility
              (LMF) features provided by VMS, and requires that a
              Product Authorization Key (PAK), be registered prior
              to installation. To register your PAK, use the command
              procedure SYS$UPDATE:VMSLICENSE.COM.

              Refer to the VMS License Management Utility Reference
              Manual for information pertaining to this command
              procedure and to management features of LMF.

              The installation procedure checks that the product is
              licensed before allowing installation to be completed. For
              an explanation of any LMF messages or errors and of any
              corresponding user actions required, see the VMS License
              Management Utility Reference Manual.

        1-2 Installation Procedures

 






              If VAX PAC is to be used in a VAXcluster environment, then
              the registered license must be loaded on each node of the
              cluster from which VAX PAC will be used.

        1.2.2 Disk Space

              VAX PAC requires the following space on the system disk:
              2400 blocks of disk space for installation and 1000 blocks
              for use.

        1.2.3 System Disk Backup

              Before you begin installing VAX PAC V1.3, you need to
              back up (make a copy of) your system disk. Backing up the
              system disk is a standard precaution before installing any

              system disk, see your VMS system management documentation.

        1.2.4 Installing in VAXcluster Environments

              If you have previously installed VAX PAC in a VAXcluster
              environment, you should perform the following steps prior
              to installing VAX PAC V1.3 if you want to preserve any
              definitions on each member of the cluster.

              1. Log in to the system manager's account for each system
                 in the VAXcluster and locate the file SYS$SYSTEM:COMM$SYSTEM.DAT.

              2. Rename the file COMM$SYSTEM.DAT:

                 $ RENAME/LOG SYS$SPECIFIC:[SYSEXE[COMM$SYSTEM.DAT
                 _To:  SYS$COMMON:[SYSEXE]COMM$SYSTEM.DAT_'f$getsyi(nodename")

                 In the above command, 'f$getsyi(nodename") is evaluated
                 to the actual node name for the system to which you are
                 currently logged.

              3. You can examine the data in this file later by using
                 the logical name COMM$SYSTEM to point to a system file
                 for a particular node. For example:

                 $ DEFINE COMM$SYSTEM SYS$COMMON:[SYSEXE]COMM$SYSTEM.DAT_MYNODE

              4. If you intend to use the system file provided with VAX
                 PAC V1.3, you should make a note of any data you have
                 entered into the system file. Use the following VAX PAC
                 manager's menu options to determine which records you
                 want to preserve:

                 GRP         SEC         STD

                 KEY         SET         SYS

                 MOD         SRV         SFR

              5. You can preserve your existing data for one node by
                 copying the file to the shared area. For example:

                 $ COPY SYS$SYSTEM:COMM$SYSTEM.DAT_MYNODE
                 _To: SYS$COMMON:[SYSEXE]COMM$SYSTEM.DAT

              If you follow this procedure, all of the data you have
              entered will be preserved.

        1.3 VMS Installation Procedure

              Use the VMS installation procedure VMSINSTAL.COM to
              install VAX PAC. This is the same procedure used to
              install all applications for VMS.

              The VAX PAC installation kit comes on 9-track magnetic
              tape or TK50 tape cartridge.

              7. After the installation is completed, go to the A-to-Z
                 Manager's Main menu.

              8. Select the Shutdown option on the A-to-Z Manager's Main
                 menu.

              9. After shutting down the system, follow the instructions
                 in the  A-to-Z Operations Guide for MicroVAX to reboot
                 the system.

        1.5 Postinstallation Requirements

              This section lists the system parameters and the
              privileges you need to use and manage VAX PAC. It
              also provides instructions for using the Installation
              Verification Procedure (IVP).

        1.5.1 System Parameters

              The SYSGEN parameter TTY_ALTYPAHD must have a value of 512
              or greater. If the value is less than 512, data overrun
              errors may occur; that is, characters from the remote
              system may be lost, especially if you use high-speed
              lines.

              The following procedure describes how to check this
              parameter and, if necessary, change it:

              1. To check the value of TTY_ALTYPAHD, enter the following
                 at the Digital Command Language (DCL) prompt:

                 $ RUN SYS$SYSTEM:SYSGEN
                 SYSGEN> USE CURRENT
                 SYSGEN> SHOW TTY_ALTYPAHD
                 SYSGEN> EXIT




        1-12 Installation Procedures

 






              2. If the value assigned to TTY_ALTYPAHD is less than
                 512, you must modify the system parameter file
                 SYS$SYSTEM:MODPARAMS.DAT and add the following line
                 at the end of the file:

                 TTY_ALTYPAHD = 512

                 (You may set a higher value if you want.)

              3. You must then run AUTOGEN to recompute your system
                 parameters:

                 $ @SYS$UPDATE:AUTOGEN SAVPARAMS REBOOT

                 AUTOGEN performs an automatic shutdown, and reboots
                 when it has finished. (For more information on
                 AUTOGEN, see the Guide to VAX/VMS Management and Daily
                 Operation.)

                ________________________Note  ________________________

                If you are using VAX PAC in a VAXcluster environ-
                ment, you need to make this change on each node in
                the cluster.

                _____________________________________________________

        1.5.2 Privileges

              Users of VAX Public Access Communications V1.3 need the
              TMPMBX (may create temporary mailbox) privilege.

              In order to use the system manager's features of VAX PAC,
              you need the following privileges:

              TMPMBX      May create temporary mailbox

              SYSPRV      May access objects via system protection

              OPER        Operator privilege

              PHY_IO      May do physical I/O

              If the spawn feature of VMS has been disabled on your
              system, you should install COMM$SYSTEM:COMM$DTE.EXE with
              SYSPRV. If you do not do so, you cannot use VAX PAC file
              transfer features.

        1.5.3 Installation Verification Procedure

              VAX PAC provides an Installation Verification Procedure
              (IVP) that allows you to check that VAX PAC has been
              installed correctly. This procedure can be run any time
              after the installation has successfully completed. This
              procedure can be run only from a privileged account.

              To run the IVP, enter the following at the DCL prompt:

              $ @SYS$TEST:COMM$IVP.COM

              The IVP checks that all the files required to use VAX PAC
              have been correctly installed on your VMS system, that
              the version numbers of the programs are correct, and that
              these programs will run.

        1.6 Modems

              Modems usually require setup before they can be used with
              VAX PAC.

              When you buy a new modem, it is often set up at the
              factory for operation with a terminal or personal
              computer. The requirements for operating the modem with
              a multiuser computer system, such as one supporting VAX
              PAC, are usually different, particularly with reference to
              dial-in to the system and breaking the phone connection.

                ________________________Note  ________________________

                The modem must hang up the phone line when the
                signal Data Terminal Ready (DTR) is dropped. If you
                use VAX PAC with a modem that does not do this, VAX
                PAC will be unable to hang up the phone, which can
                cause you to incur excessive phone charges.

                _____________________________________________________

        1-16 Installation Procedures

 






              The setup method varies with the type of modem. Some
              modems require switches to be set within the modem.
              Others require you to enter commands from the terminal.
              In the latter case, some modems require the commands to
              be entered every time power is turned on, while others
              allow the settings to be stored permanently. Your modem
              documentation describes the procedures for changing the
              setup of your modem.

              See Appendix C and Appendix D for additional details on
              modem setup and commands.

              You can use most types of modems to communicate with a
              remote system. VAX PAC supports the following modems:

              o  Digital Scholar 2400 (DF224)

              o  Digital Scholar Plus (DF242)

              o  Digital DF112

              o  Digital DFA01

              o  Digital DF03 and DF03 compatible modems

              o  Hayes Smart Modem 2400 and Hayes Smart Modem 1200

              See Appendix E for information on using a DTE_DF03, DTE_
              DF112, or DMCL dial module with a DMF32 controller.

              If you have a different type of modem, you must use the
              MOD-Define modems option. See Section 2.5.3 to enter the
              information for that modem.

                ________________________Note  ________________________

                For VAX Public Access Communications to work, you
                must use the correct modem connecting cable. A cable
                not certified for use with your modem can lead to
                faulty connections.

                _____________________________________________________

        1.7 Installing Modems

              It is important that you identify the proper port before
              attaching the modem to the back of your system.

              You are already familiar with ports because you used at
              least two ports to attach your terminal and printer to
              your system. You can use any of the remaining ports to
              connect modems.

              Each port has a device name. When you use the SET option
              on the Manager's Main menu to set up communication lines,
              you must be able to identify the device name assigned to
              the port to which you attach the modem. The following
              section helps you determine which device names are
              assigned to the ports and how you can identify them.

              Enter the following DCL command to determine the device
              name for the ports on your system:

              $ SHOW DEVICE T

              The system displays a listing of the device names.
              Examples of device names are as follows:

              TXA0 thru TXA7 (1st 8 lines)
              TTA0 thru TTA3 (1st 4 lines)

              To find out which device name is associated with a
              particular port on your system, follow these steps:

              1. Disconnect your terminal cable connection from its port
                 on the system.

              2. Temporarily attach your terminal cable connection to
                 the port on the system where you will be attaching the
                 modem.

              3. Log in to your system.

              4. Enter the following DCL command:

                 $ SHOW TERMINAL

                 The system displays a screen showing your terminal
                 characteristics, including Physical Terminal or
                 Terminal followed by a device name. This is the
                 device name of the port to which your terminal is now
                 attached. For example, if your terminal is attached

        1-18 Installation Procedures

 






                 to TXA3, this is the device name that appears next to
                 Physical Terminal or Terminal. Make note of this device
                 name, because you must enter this device name when you
                 use the SET option on the Manager's Main menu to set up
                 communication lines.

              5. Log out.

              6. Switch your terminal cable connection back to its
                 original port on your terminal.

              7. Attach the modem cable to the port on the system you
                 identified when checking for device name. Use a Digital
                 BC22E, BCC04, or equivalent cable to connect the modem
                 to the system. Refer to the documentation for your
                 modem for complete information on connecting the modem.

              8. Log in.

              If you are using VAX PAC in a VAXcluster environment, you
              must log in to each system within the cluster that will
              have a modem attached to it.

        1.8 Testing Modem Connections

              Test all connections before attempting to use VAX PAC. It
              is essential that you be able to communicate between your
              system and the remote system through the modem.

              In most cases, the modem is connected to your system
              with a special cable. This cable must be connected to
              the proper port on your system. Check that the cable
              connecting your modem and system is the proper one.
              Digital recommends that you use a Digital BC22E or
              BCC04 cable. Your modem installation guide might list
              alternatives.

              Figure 1-1 shows a typical standalone modem and its
              connections, including the power outlet, telephone
              handset, wall outlet connections, and terminal.





                                            Installation Procedures 1-19

 







              These connections might differ depending on the type of
              modem you are using. Refer to your modem installation
              guide for instructions.

              To test modem connections, you need a phone number you can
              dial. The phone number for the Digital Electronic Store
              is readily available and can be used for this test. Dial
              1-800-DEC-DEMO (800-332-3366).

              There are two ways to test modem connections:

              o  Connect the modem to the communication port on your
                 terminal and test connections at your terminal.

              o  Use VAX PAC.





























        1-20 Installation Procedures

 






              The following sections explain how to test connections
              using each method. Note that testing connections with VAX
              PAC is usually easier, but it does require some knowledge
              of VAX PAC.

                ________________________Note  ________________________

                If you are using a workstation, you must use VAX
                PAC for testing connections. Tests described in
                Section 1.8.2 cannot be used with a workstation.

                _____________________________________________________

        1.8.1 Testing Modem Connections with a Terminal

              Follow these steps to test for proper connection of your
              modem using a VT300, VT200, or VT100 series terminal:

              1. Unplug the modem from your system.

              2. Temporarily connect the modem to the communications
                 port on your terminal. Read the instructions supplied
                 with your modem and terminal carefully and be sure to
                 plug the modem into the proper terminal port.

              3. Set the terminal speed to match the modem speed. Refer
                 to your terminal and modem documentation.

              4. Test the power supply for your modem by turning on the
                 modem and the terminal. Lights on the modem blink to
                 indicate the power supply is properly connected.

                 An indicator light (TR or DTR) should remain lit. This
                 means your terminal is ready.

                 Refer to your modem installation guide for further
                 instructions.

              5. Check your phone connections. Refer to your modem
                 installation guide for instructions on checking phone
                 connections.

              6. Check that your modem is able to send back data that
                 you type from the terminal. Do this by first pressing
                 the Local Loop Back switch on your modem and then
                 typing something at your terminal. The characters typed
                 should display on the terminal screen.

                                            Installation Procedures 1-21

 






              7. Check that your modem can actually connect to another
                 modem. Use the handset to dial and wait for a high-
                 pitched carrier tone. When you hear the carrier tone,
                 set the Data/Talk switch on the modem to the Data
                 position. For example, dial the Digital Electronic
                 Store (1-800-332-3366) and test your connections.
                 (If your modem does not have a Data/Talk switch,
                 refer to your modem installation guide for further
                 instructions.) The carrier tone should stop when the
                 Data/Talk switch is in the Data position.

              8. If your modem has an autodial feature, you can
                 also connect to another modem. Refer to the modem
                 documentation for information on its autodial feature.

                 For example, with the Digital DF224, press Ctrl/B.
                 The Ready message is displayed. Type 1-800-332-3366!
                 (include the exclamation point to indicate the end of
                 the dial command). The Attached message is displayed.

              9. When testing is complete, reconnect the terminal and
                 modem to the system.

        1.8.2 Testing Modem Connections with VAX PAC

              Follow these steps to test modem connections using VAX
              PAC:

              1. Before testing a modem using VAX PAC, you must first
                 set up a communication line. Select the SET option
                 from the Main menu to set up a communication line.
                 Section 2.4.1 explains this option.

              2. Select the CON option from the Main menu to connect
                 to a remote system. See the VAX Public Access
                 Communications (VAX PAC) User's Guide for information
                 about the CON option.

              3. Select MAN for a manual connection. The VAX Public
                 Access Communications (VAX PAC) User's Guide explains
                 manual connections.

              4. Select Expert Dial mode. This allows you to enter modem
                 commands as if your terminal were directly connected to
                 the modem.

              6. Test the power supply for your modem by turning on the
                 modem and the terminal. Lights on the modem blink to
                 indicate the power supply is properly connected.

                 An indicator light (TR or DTR) should remain lit. This
                 means your terminal is ready.

                 Refer to your modem installation guide for further
                 instructions.

              7. Check your phone connections. Refer to your modem
                 installation guide for instructions on checking phone
                 connections.

              8. Check that your modem is able to send back data that
                 you enter from the terminal. Do this by first pressing
                 the Local Loop Back switch on your modem and then
                 typing something at your terminal. The characters
                 should be displayed on the terminal screen.

              9. Check that your modem can actually connect to another
                 modem. Use the handset to dial and wait for a high-
                 pitched carrier tone. When you hear the carrier tone,
                 set the Data/Talk switch on the modem to the Data
                 position. For example, dial the Digital Electronic
                 Store (1-800-332-3366) and test your connections.
                 (If your modem does not have a Data/Talk switch,
                 refer to your modem installation guide for further
                 instructions.) The carrier tone should stop when the
                 Data/Talk switch is in the Data position.

              10.If your modem has an autodial feature, you can
                 also connect to another modem. Refer to the modem
                 documentation for information on its autodial feature.

                 For example, with the Digital DF224, press Ctrl/B.
                 The Ready message is displayed. Enter 1-800-332-3366!
                 (include the exclamation point to indicate the end of
                 the dial command). The Attached message is displayed.

              11.Press the LOCAL key to disconnect from the remote
                 system.

              12.Press Exit.

                               Managing VAX Public Access Communications



              This chapter explains how to manage VAX PAC.

        2.1 Getting Started

              VAX PAC runs on a VMS system or an A-to-Z system. Follow
              the instructions in this section to start VAX PAC on your
              system.

              The minimum requirements for VAX PAC are listed in
              Chapter 1.

        2.1.1 Starting VAX PAC on VMS

              If you are using a VMS operating system, do the following:

              1. Log in to the system manager's account.

              2. Enter the COMMUNICATE command at the Digital Command
                 Language (DCL) prompt ($). You can also enter an
                 abbreviated form of the command, such as COMM or COMMU.
                 After you enter the command, the VAX PAC Manager's Main
                 menu is displayed.

                ________________________Note  ________________________

                Use the DCL command HELP COMMUNICATE for a full list
                of options available from the DCL prompt ($).

        2.1.2 Starting VAX PAC on A-to-Z

              If you are using an A-to-Z system, do the following:

              1. Log in to the A-to-Z manager's account.

              2. Display the A-to-Z User's Main menu or the A-to-Z
                 Application Management menu.

              The A-to-Z User's Main menu contains two entries for VAX
              Public Access Communications:

                 COM Public Access Communications
                 REM Remote File Transfer Server

              Both of these entries are also available on the A-to-Z
              User's Interrupt menu.

              The Application Management menu contains an entry for
              Managing Communications:

                 COM Managing Communications

              Refer to the appropriate A-to-Z documentation and
              follow the directions to begin using VAX Public Access
              Communications.

        2.2 VAX PAC Manager's Main Menu

              The VAX PAC Main menu and the VAX PAC Manager's Main menu
              are different:

              o  The Main menu displays only options associated with the
                 Using Communications and Miscellaneous functions.

              o  The Manager's Main menu displays the same options and
                 options for managing and customizing communications.

              When you use VAX Public Access Communications for the
              first time, select the INT-Introduction to VAX Public
              Access Communications option from the Manager's Main menu.
              The INT option gives an overview of the capabilities of
              VAX Public Access Communications.

              In addition to the physical connections you must make, you
              must also enter information to set up VAX PAC. To do this,
              enter the COMMUNICATE command at the DCL prompt. If you
              are using A-to-Z, select the Application Management menu
              from the Manager's Auxiliary menu, and then choose the
              Managing Communications option.

              Figure 2-1 shows the VAX PAC Manager's Main menu.

              The options shown under Using Communications are described
              in detail in the VAX Public Access Communications (VAX
              PAC) User's Guide. Use these options to communicate with
              remote systems.

              The options shown under Miscellaneous are also described
              in detail in the VAX Public Access Communications (VAX
              PAC) User's Guide.

              Use the options shown under Managing Communications to set
              up and maintain VAX PAC. These options (SET, GRP, STD) are
              described in Section 2.4.

              Use the options shown under Customizing Communications
              to tailor VAX PAC to your own requirements. These
              options (SYS, SEC, MOD, XFR, SRV, KEY) are described in
              Section 2.5.

        2.3 Operating Features

              This section explains how to use various keys to set field
              values, how to edit fields, and the use of the LOCAL key.

        2.3.1 Entering Field Values

              VAX Public Access Communications uses a variety of field
              values to operate and configure the system. These values
              are displayed as fields on screens. To respond to the
              fields on the screen, use the keys described in this
              section.

              A keystrip for VT200/VT300 terminals is included as part
              of the VAX PAC installation kit.

              o  Enter information for any fields that have an underline
                 to the right of the field; for example:

                 Phone number: ____________________

              o  Use the left (< - ) or right (- > ) arrow keys to
                 change the values enclosed in angle brackets:

                 <Fields like this>

              o  Use the Return key, the up arrow ( ^ ) key or the down
                 arrow (v ) key to move between fields.

                           Managing VAX Public Access Communications 2-3

 






              o  When you are not sure how to respond, press the Help
                 key.

              o  Press the Do key to confirm selections or accept
                 information when all the fields for a screen are
                 complete.

              o  Press the Exit key or the F10 key to return to the
                 previous menu or screen or to exit from VAX PAC at the
                 Main menu. Changes are saved.

              o  Press Cancel or the F8 key when you want the system to
                 ignore a selection or disregard information you have
                 entered.

              o  The PF1 key or GOLD key is used in conjunction with
                 other keys to simulate VT200 or VT300 function keys
                 on VT100 series terminals. The the PF1 key or GOLD key
                 is always pressed first. For example, pressing PF1 and
                 then P on a VT100 keyboard is equivalent to pressing
                 the Prev Screen key on a VT200 or VT300 keyboard.

              o  Control keys are a combination of Ctrl and another
                 key pressed simultaneously. Control keys are used to
                 simulate the VT200 or VT300 function keys on VT100
                 series terminals. For example, Ctrl/Y on the VT100 is
                 equivalent to the Interrupt key or the F6 key on the
                 VT200 or VT300 keyboard.

              o  Press the Find key to display a list of files.

              o  Press the Insert Here key to add a new record.

              o  Press the Remove key to delete an existing record.

              o  Press the Interrupt key or the F6 key to start the
                 interrupt procedure.

              o  Press the Resume key or the F7 key to continue after
                 receiving an informational message.

              See Appendix B for a listing of all function keys
              available for use with VAX PAC. To get online help on
              the function keys, press the PF2 key.

        2.3.3 The LOCAL Key

              Use the LOCAL key when a connection to a remote system has
              been established. You use the LOCAL key either to end a
              session or to access any of the other options available
              during a connection to a remote system.


                           Managing VAX Public Access Communications 2-5

 






              The default LOCAL key is actually two keys, Ctrl and \,
              pressed simultaneously. The system manager can change the
              default for the LOCAL key.

              The Local Options menu (Figure 2-2) is displayed when you
              press the LOCAL key.

              The VAX Public Access Communications (VAX PAC) User's
              Guide explains the LOCAL key in detail.

                ________________________Note  ________________________

                If you select option I-Interrupt from the Local
                Options menu and use the interrupt procedure while
                connected to a remote system, you do not terminate
                your link to that system. You continue to incur
                telephone and access charges while engaged in your
                interrupt procedure. To discontinue a link to the
                remote system, you must exit from your interrupt
                procedure, press the Resume key to return to VAX
                PAC, and then end the session by selecting option
                E-End session from the Local Options menu.

                _____________________________________________________

        2.4 Management Options

              The Manager's Main menu allows you to set up communication
              lines, to set up groups of communication lines, and
              to define standard connections. These menu options are
              explained in the following sections.

        2.4.1 SET-Set Up Communication Lines

              VAX PAC does not allow you to connect to a remote database
              until you have set up communication lines. Use the SET
              option to set up communication lines. VAX PAC allows a
              maximum of 64 communication lines.







        2-6 Managing VAX Public Access Communications

 






              Setting up a communication line requires the following
              information:

              o  The name of the line

              o  The node name, if used in a VAXcluster environment

              o  The device name for the port

              o  Whether a phone line or a direct connection is used

              o  The type of modem

              o  The type of phone service

              o  The line speed to be used when dialing

              o  Whether or not to disable the line

              You can add, change, delete, or display communication
              lines. If no communication lines are defined when you
              select SET from the Main menu, a screen for adding a new
              communication line is displayed. Thereafter, when you
              select the SET option, a list of the communication lines
              you have already set up is displayed.

              The following list shows the types of modems that are
              already defined as part of the VAX PAC software. If you
              are using a modem other than the types listed here, read
              Section 2.5.3 before proceeding.

              o  Digital Scholar 2400 (DF224)

              o  Digital Scholar Plus (DF242)

              o  Digital DF112

              o  Digital DFA01

              o  Digital DF03 compatible modems

              o  Hayes Smart Modem 2400

              o  Hayes Smart Modem 1200

              (See Appendix E for information on using a DTE_DF03, DTE_
              DF112, or DMCL dial module with a DMF32 controller.)

              Figure 2-3 is the screen used for adding a communication
              line. Following the sample screen are explanations of each
              field.

        Name for      Enter a name of up to 30 characters for the
        commu-        communication line. If the communication line uses
        nication      a modem, it is a good idea to specify the modem's
        line:         line speed as part of the name. If the name of the
                      communication line includes the line speed for the
                      modem to which the line is attached, you can then
                      know if this is the correct line speed for the
                      connection.

        Node name:    If you are using VAX PAC in a VAXcluster
                      environment, enter the node name where the device
                      is located. If you are not using VAX PAC on a
                      cluster, leave this field blank.

        Device name:  Enter the device name of the communication port to
                      which the modem or the remote system is directly
                      connected; for example, TXA3:, TTA1:, or TXB4:.
                      If you are not sure of the device name, see
                      Section 1.7 to identify the device name.

        Line type:    Specify that the communication line is either a
                      phone line or a direct connection.

        Modem type:   Identify the type of modem you are using.
                      As you add and define modems (explained in
                      Section 2.5.3), they are automatically listed
                      on the modem screen.

        Pulse/Tone    Your response to this field depends on the type of
        dialing:      telephone service you have (pulse or tone). Push-
                      button phones use tone dialing. Rotary dial phones
                      use pulse dialing. Digital modems are equipped to
                      handle both pulse and tone dialing.

        Transmit      Specify the speed at which the modem can receive
        speed:        characters from the local system. This speed is
                      specified in the modem documentation.




        2-8 Managing VAX Public Access Communications

 







        Receive       Specify the speed at which the modem will send
        speed:        characters to the local system. This speed is
                      specified in the modem documentation.

        Disabled?     Specify Yes if you need to disable the communica-
                      tion line due to a problem with the phone line or
                      modem. When you disable a line, it is available
                      only to the system manager. A disabled line is
                      ignored in all groups of communication lines that
                      reference it.

                ________________________Note  ________________________

                The transmit and receive speeds you specify are
                used when dialing the remote system. Depending on
                the modem type, these speeds can be superseded by
                the speeds you specify for the connection when the
                remote system has answered. In other words, the
                transmit and receive speeds are current only until
                the remote system answers.

        2.4.2 GRP-Group Communication Lines

              The GRP option lets you combine up to 12 communication
              lines into one group. This allows VAX PAC to reach a
              remote system using any communication line in the group.
              For example, if one communication line in the group
              is being used by someone else, VAX PAC uses the next
              available line in the group to reach the remote system.

              If you have more than one modem or several direct
              connections to the same system, use this feature.

              You can add, change, delete, or display communication
              lines. If no communication lines are defined when you
              select GRP from the Main menu, a screen for adding a new
              communication line is displayed. Thereafter, when you
              select the GRP option, a list of the communication lines
              you have already set up is displayed.

                 communication lines.

        2.4.3 STD-Define Standard Connections

              To make any connection available to all users of the
              system, define it as a standard connection. When you
              define a connection, all the details required to establish
              the connection are stored. Standard connections are
              displayed among the list of connections when the CON
              option is selected from the Main menu.

              As the system manager, you can set up personal and
              standard connections using the appropriate Main menu
              options (PER for personal connections, STD for standard
              connections).

              A shortcut to create either type of connection is to use a
              manual connection. Manual connection is displayed when you
              select the CON option from the Main menu.

              You can do the following if you select manual connection:

              o  Enter the information required to make the connection
                 to a remote system. This involves identifying the
                 communication line you want to use, the telephone

        2-12 Managing VAX Public Access Communications

 






                 number of the remote system, the transmit and receive
                 speeds, and other information.

              o  After you enter the information for the connection, you
                 can make the actual connection to the remote system.
                 This is a good way to test whether you have set up the
                 connection properly.

              o  When you are finished with a manual connection, you are
                 prompted by the system whether to save the definitions
                 for that connection. You can save the connection as
                 either a personal connection or a standard connection.

              o  The connection you saved is displayed in the list of
                 available connections. You can either select this
                 connection to connect with the remote system or use
                 a manual connection again to connect with a different
                 remote system.

              You can add, change, delete, or display standard
              connections. If no standard connections are defined when
              you select STD from the Main menu, a screen for adding
              a standard connection is displayed. Thereafter, when you
              select the STD option, a list of the communication lines
              you have already set up is displayed.

              Figure 2-5 is the screen used for adding a standard
              connection. Following the sample screen are explanations
              of each field.

              The following sections explain how to respond to each
              field on the screen.

        Name for      Enter a name to identify the connection; for
        connection:   example, "Dow Jones" or "Branch Office." The name
                      you enter here is displayed among the list of
                      connections that can be made when you select the
                      CON option from the Main menu.

        Phone         If you are using a modem to reach the remote
        number:       system, enter the telephone number of the remote
                      system. If necessary, include the area code. You
                      can enter up to 30 numeric characters. Alphabetic
                      characters as they appear on the dialer are not
                      allowed. Use the numeric equivalent. You can
                      enter the number with or without separators. For
                      example, either of the following is correct: (999)
                      999-9999 or 9999999999.

                      Sometimes it may be necessary to wait for a
                      secondary dial tone when dialing. To do this,
                      enter %W where you want the pause. Some long
                      distance companies require this feature. For
                      example, you may need to dial 9 for an outside
                      line, pause, and then dial the phone number. To do
                      this, enter the following:

                      9-%W-(123)-999-9999

        Dial method:  Specify the type of dialing you want to use
                      to reach remote systems. The type of modem
                      you have, your own expertise with your modem's
                      capabilities, and the remote system determine the
                      type of dialing you use. Consider the following
                      possibilities:

                      o  If your modem has autodial capabilities, this
                         means the modem can dial the number for you.
                         In this case, select the Use computer dialing
                         option.

                      o  If your modem does not have autodial capabil-
                         ities, you must specify the Dial from handset
                         option.

                      o  If someone at the site of the remote system
                         must answer the telephone to allow you to
                         continue, you should also specify the Dial
                         from handset option.

                      o  If you are experienced at using your modem
                         and you want to take advantage of your modem's
                         unique setup and special dial features, select
                         the Use Expert Dial mode option.

        Communication Use this field to assign a communication line to
        line:         your connection. The values enclosed within angle
                      brackets show the name of a communication line
                      or group of communication lines. Use < - or - >
                      to select a different communication line (if more
                      than one communication line is available).

                ________________________Note  ________________________

                You usually do not have to change the following
                fields. These fields are automatically set by the
                system.

        Session       Use Disabled if you do not want the system to log
        logging:      (save) the information displayed by the remote
                      system. Use Enabled if you want to log this
                      information. You can temporarily enable logging
                      while connected to a remote system by using the
                      Local Options menu. You can also change logging
                      status during a session by using this same menu.

        Logging       This field specifies the format of the session
        mode:         logging data you want to save. Use Record if you
                      receive information from the remote system one
                      line at a time. Use Image if the data contains
                      control characters, such as screen displays (for
                      example, a menu screen). Record is the usual
                      setting.

        Timeout       This field shows the number of seconds allowed for
        (secs):       VAX PAC to establish a connection with the remote
                      system. If the connection is not made within this
                      time, a message is displayed.

        Transmit      To set the transmit speed, you must know the
        speed:        receive speed of the remote system. Use this field
                      to match your system's transmit speed with the
                      remote system's receive speed. Use < - or - >
                      to change the transmit speed. For example, if the
                      remote system's receive speed is 1200, select 1200
                      as your transmit speed. Initially, the transmit
                      speed is Same as communication line.

        Receive       To set the receive speed, you must know the
        speed:        transmit speed of the remote system. Use this
                      field to match your system's receive speed with
                      the remote system's transmit speed. Use < - or
                      - > to change the receive speed. For example, if
                      the remote system's transmit speed is 1200, select
                      1200 as your receive speed. Initially, the receive
                      speed is Same as communication line.

                      this field if the text displayed on the remote
                      system is displayed crowded on the line.

        Character     This field is used to specify the length of the
        size:         characters you send and receive from a remote
                      system. It can be either 7 or 8 data bits. Use
                      < - or - >  to change this field.

        Parity:       Parity can be None, Even, Odd, or Space. Parity is
                      a means of checking that the data sent from one
                      system is received correctly by another system.
                      Use < - or - >  to change this field.

        XON/XOFF      All Digital terminals and systems support this
        support?      feature. The XON/XOFF feature is used to recognize
                      when and when not to send characters. Use < -

                      select Yes for this field. However, most systems
                      do not require local echo. If you select No, the
                      remote system displays each character. Use < - or
                      - > to select the response.

        File          This field specifies the file transfer method you
        transfer:     can use to transfer files between your system
                      and the remote system. When VAX PAC is first
                      installed, KERMIT is the only method of file
                      transfer available. If you want to use another
                      file transfer method, you must install it.
                      (Section 2.5.4 explains this procedure.) If you
                      install another file transfer method, use < - or
                      - > to select it.

        LOCAL key:    This field specifies the key that is used to
                      return control from the remote system to your
                      system. The default LOCAL key is actually two
                      keys, Ctrl and \, pressed simultaneously. Use < -
                      or - > to select a different value for the LOCAL
                      key.

        Swap          If you select this option, the definitions of
        Backspace     the Backspace and Rubout key are reversed. This
        and Rubout    means when you press the Rubout key, the control
        keys?         character for Backspace, Ctrl/H, is passed to the
                      remote system. If you press either Backspace or
                      Ctrl/H, the control character for Rubout is passed
                      to the remote system.

              After you enter the information, press Do to set up your
              first standard connection.

        2.5 Customizing Options

              In addition to the management options, the Manager's Main
              menu provides you with the following options to customize
              VAX PAC to meet any special requirements of your system:

              o  Set system defaults

              o  Choose security options

              o  Define modems

              o  Define methods of file transfer

              o  Define remote file transfer servers

              o  Define Interrupt key procedures

              The following sections describe these menu options.

        2.5.1 SYS-Set System Defaults

              System defaults are used when you first define a new
              connection. Although the system defaults are already set
              for general use, you might need to change them. The system
              defaults include the interrupt procedure, and the transmit
              and receive speeds.

              A screen similar to Figure 2-6 is displayed when you
              select the SYS option. When VAX PAC is first installed,
              the system defaults are the same as shown on this screen.
              Following the sample screen are explanations of each
              field.

              Follow these steps to change defaults:

              1. Select the default you want to change by positioning
                 the cursor over the existing value. Use ^  or v  to
                 position the cursor.

              2. Select a new value by using < - or - >  to change the
                 values enclosed in angle brackets. If the defaults are
                 not enclosed in angle brackets, enter the values using
                 the keyboard.

              3. Press Do to save the new values or press Cancel for the
                 system to ignore any changes. VAX PAC then returns you
                 to the Main menu.

              The following sections explain how to respond to each
              field on the screen. Press Help if you are not sure how to
              respond.

        Startup       This field allows you to specify the first screen
        option:       displayed by VAX PAC. The value you specify is
                      used only when VAX PAC is started using the DCL
                      command COMMUNICATE with no other qualifiers.

                      If you select User's Main Menu, VAX PAC displays
                      the User's Main menu when you start VAX PAC, even
                      if you are operating from a privileged account. If
                      you select this option and later want to use the
                      Manager's Main menu in a session, you must start
                      VAX PAC with the command COMMUNICATE/SYSTEM.

                      If you select Default Main Menu, the menu
                      displayed when you start VAX PAC depends on your
                      privileges. Normally, VAX PAC displays the User's
                      Main menu. If you are operating from a privileged
                      account, VAX PAC displays the Manager's Main menu.

                      If you select Connect to Remote System, VAX PAC
                      bypasses all Main menus and displays the list of
                      available connections. If you select this option
                      and later want to use a Main menu, you must start
                      VAX PAC with the command COMMUNICATE/USER (for the
                      User's Main menu) or COMMUNICATE/SYSTEM (for the
                      Manager's Main menu).

        File          This field specifies the file transfer method you
        transfer:     can use to transfer files between your system
                      and the remote system. When VAX PAC is first
                      installed, KERMIT is the only method of file
                      transfer available. If you want to use another
                      file transfer method, you must install it.
                      (Section 2.5.4 explains this procedure.) If you
                      install another file transfer method, use < - or
                      - > to select it.

        Interrupt     This field allows you to select the interrupt
        procedure:    procedure you can use when you press the interrupt
                      key. VAX PAC comes with the Spawn DCL procedure
                      already installed, although you can define other
                      procedures as described in Section 2.5.6. When you
                      use Spawn DCL, you must log out to get back into
                      VAX PAC.

        Field         If you select No for this field, whenever you
        Editing:      enter a value in a field, the previous value is
                      erased. You can, however, use the erase keys when
                      entering a new value.

                      If you select Yes for this field, you can edit a
                      value for a field that you have previously typed
                      using the cursor movement keys in addition to the
                      erase keys.

                      Section 2.3.2 explains the function keys to use
                      when field editing is enabled.

        LOCAL key:    This field specifies the keys you use to return
                      control from the remote system to your system.
                      The default LOCAL key is actually two keys, Ctrl
                      and \, pressed simultaneously. You can select an
                      alternative LOCAL key (such as Ctrl/P) by using
                      < - or - > . Section 2.3.3 explains the LOCAL
                      key.

        Timeout       The value you specify in this field determines
        (secs):       how long the system waits for a connection to
                      be established before giving up the attempt to
                      connect.

        Characters    When VAX PAC is installed, the following
        ignored       characters are disregarded in a telephone number:
        in phone       []   brackets
        numbers:      ()   parentheses

                           blank spaces

                      -    hyphen

                      .    period

                      Alphabetic characters as they appear on the dialer
                      are not allowed. Use the numeric equivalent.

                      Use this field to enter any additional characters
                      you want the system to disregard.

        Transmit      This field specifies the speed at which your modem
        speed:        can send characters over the telephone lines.
                      This depends entirely on the speed at which your
                      modem is capable of sending characters. The value
                      here is used as the default when you define a new
                      connection.

        Receive       This field specifies the speed at which your modem
        speed:        can receive characters from the remote system.
                      This depends entirely on your modem, but the
                      receive speed is almost always the same as the
                      transmit speed. The value here is used as the
                      default when defining a new connection.

        Automatic     Use No if you do not want a line feed added to
        newline?      each line displayed on the remote system. Use < -
                      or - > to change this field to Yes if you want a
                      line feed added to each new line. Select Yes for
                      this field if the text displayed from the remote
                      system is displayed crowded on the line.







                          Managing VAX Public Access Communications 2-23

 







        Character     You should know the character size (either 7 or 8
        size:         data bits) used by the remote systems with which
                      you want to communicate. This field is used to
                      specify the length of the characters you send and
                      receive from a remote system. Use < - or - >  to
                      change this field.

        Parity:       You should know the type of parity that is being
                      used by the remote systems with which you want
                      to connect. Parity can be either None, Even, Odd,
                      or Space. Parity is a means of checking that the
                      data sent from one system is received correctly
                      by another system. Use < - or - >  to change this
                      field.

        XON/XOFF      You should know if the remote system has the
        support?      XON/XOFF feature. All Digital terminals and
                      systems support this feature. The XON/XOFF feature
                      is used to recognize when and when not to send
                      characters. Use < - or - >  to change this field
                      to No if the remote system does not have the
                      XON/XOFF feature.

        2.5.2 SEC-Security Options

              The VAX PAC system manager can set security options
              that restrict access to phone features and Interrupt key
              features.

              When you select the SEC option from the Manager's Main
              menu, a screen similar to Figure 2-7 is displayed.













        2-24 Managing VAX Public Access Communications

 







        2.5.2.1 Restricting Access to Phone Features

              Use the following security options to restrict access to
              phone features:

              o  Allow Users to Define Personal Connections?

                 The default Yes allows users to define personal connec-
                 tions. Users can then define their own connections when
                 accessing a remote database.

                 If you select No, users can use only standard
                 connections when accessing a remote database.
                 Users cannot use the PER option to define personal
                 connections, and cannot choose manual connections from
                 the CON option.

                 This option is useful in restricting the number and
                 type of personal connections that you allow users.

              o  Allow Users to Specify Dial Method?

                 The default Yes allows users to select the method of
                 dialing when defining a connection.

                 If you select No, you restrict users to computer
                 dialing when defining the connections. Users cannot
                 dial from the handset (telephone) or use expert mode
                 dialing.

                 This option is useful in restricting the number and
                 type of dialing methods that you allow users.

        2.5.2.2 Restricting Access to Interrupt Key Features

              Use the following security options to restrict access to
              Interrupt key features:

              o  Allow Users to Use Interrupt Procedure?

                 The default Yes allows users to press the Interrupt
                 key to suspend the VAX PAC session and start their own
                 interrupt procedure.

                 If you select No, the use of the Interrupt key is
                 disabled.

                 This option is useful in preventing users from
                 suspending their connection to the remote database
                 in favor of other activities.

              o  Allow Users to Change Interrupt Procedure?

                          Managing VAX Public Access Communications 2-25

 






                 The default Yes allows users to choose any procedure
                 from the available interrupt procedures.

                 If you select No, users cannot change the defined
                 interrupt procedure invoked by pressing the Interrupt
                 key.

                 This option is useful for defining the interrupt
                 procedure to which individual users have access. For
                 example, you may want to restrict A-to-Z users to the
                 A-to-Z Interrupt menu.

        2.5.3 MOD-Define Modems

              You need not use this option if you intend to use any of
              the modems already defined for VAX PAC. Section 1.5 lists
              those modems already defined for VAX PAC.

              To use a modem other than one defined for VAX PAC, you
              must use the MOD option to enter the information for
              the new modem. When you select MOD, a screen similar to
              Figure 2-8 is displayed:

              The modems shown on the screen are those that have been
              tested for use with VAX PAC. To add a new modem to the
              list, you must press Insert Here. Later, you can press
              Do to display or change the information for any modem, or
              Remove to delete the information for any modem.

              You can add, display, change, or delete modem definitions.
              If no modems are defined when you select MOD from the
              Main menu, VAX PAC displays a screen for adding a new
              modem. Thereafter, when you select the MOD option, VAX PAC
              displays a list of the modems you have already set up.

              Refer to your modem setup guide for information on
              defining modem characteristics. The Software Product
              Description (SPD) supplied as part of the VAX PAC
              installation kit lists the modems supported by VAX PAC.

              Figure 2-9 is an example of the screen used for adding
              a modem. Following the sample screen are explanations of
              each field.

              field on the screen. Press Help if you are not sure how to
              respond.

        Modem name:   Give each modem a unique name of up to 30
                      characters. When you set up a communication line,
                      the name you give the modem is displayed in the
                      list of available modems.

        Dial module:  A dial module is a type of software that can
                      communicate with a modem. VAX PAC has two built-in
                      dial modules. They are:

                      o  GENERIC-The most flexible of the dial modules.
                         A connection is treated as successful when the
                         carrier is detected. An unsuccessful connection
                         occurs when you press Cancel before the carrier
                         is detected or when the carrier is not detected
                         within the time allowed for the connection.
                         Select the GENERIC dial module if you are using
                         a DMF32 controller (see Appendix E).

                      o  DMCL-This dial module supports Digital's Modem
                         Command Language (DMCL) and is specific to
                         the DFA01 and the Digital Scholar Plus (DF242)
                         modems. The module can take advantage of the
                         special features of Digital modems supporting
                         DMCL, such as automatic speed matching.

                      In addition to the dial modules listed here, VAX
                      PAC can use the dial modules supplied with VMS for
                      the DCL command SET HOST/DTE (for example, DTE_
                      DF03 for the DF03 modem). The source program file
                      SYS$EXAMPLES:DTE_DF03.MAR is provided with VMS as
                      an example of such a dial module.

        dialing?      Some older modems do not allow this feature and
                      require the use of a telephone handset.

                      If your modem supports computer dialing, select
                      Yes. Otherwise, select No.

        Does dial     Some modems can match transmission speeds with the
        module        modem on the remote system. Not all dial modules

        matching?     Any values you have selected for the connection

                      are ignored.

                      If you select No, then the speed you specify for
                      the connection is used once a connection has been
                      established. It is important that this be the
                      actual speed for the connection. You can change
                      the speed once a connection has been established
                      by using the Change Setup option on the Local
                      Options menu displayed when you press the LOCAL
                      key.

                      The DMCL dial module supports speed matching.
                      When using the GENERIC dial module, DTE_DF03 or
                      DTE_DF112, you must specify the speed for the
                      connection when the connection speed is different
                      from the speed set for the communication line.

        Maximum       It is usually necessary to keep the rate at which
        transfer      commands are passed to the modem low so that the
        rate for      modem does not lose data. Some modems can accept
        commands      commands at 100 characters per second, but others
        (chars/second)require 10 characters per second.

                      The value you enter here is the maximum number of
                      characters per second that your modem can accept
                      without losing data. A value of zero is treated as
                      20 characters per second.

                      If you have problems losing data when sending
                      commands such as setup or when dialing, you can
                      either reduce the transfer rate specified here, or
                      you can add the characters ^w to introduce pauses
                      of half a second.

        Dial          The dial command is used to dial the remote system
        command:      when you select computer dialing. The information
                      you enter here depends on the dial module you are
                      using. The GENERIC dial module allows you to use
                      VAX PAC commands within the dial command. The DMCL
                      dial module requires only the VAX PAC codes %P and
                      %D, which represent the dial type (tone or pulse)
                      and phone number to be dialed.

                      The dial command requires special values that
                      you need to understand. These are explained in
                      Appendix D.

                      The following example shows the dial command for
                      the Scholar 2400 using the GENERIC dial module:

                      ^B^w^r^tDialing %M^M^J^z%P%D!

                      o  ^B-The control sequence Ctrl/B lets you enter
                         Scholar command mode

                      o  ^w-Wait 1/2 second for modem to respond

                      o  ^r-Wait for modem response

                      o  ^tDialing %M^M^J^z-Displays the message
                         containing the unedited phone number followed
                         by a carriage return and a line feed

                      o  %P-Selects either tone dialing or pulse
                         dialing, depending on what you have specified

                      o  %D-The phone number with any redundant
                         characters removed

                      o  !-End of dial command

        Start expert  You may need to enter commands directly to the
        dialing:      modem. Use expert dialing for this.

                      The modem is usually set up to allow computer
                      dialing for outgoing calls and automatic answering
                      of incoming calls. This setup often means that
                      commands typed to the modem are not displayed on
                      the terminal.

                      To use expert dial mode, specify any commands
                      needed to allow you to interact with the modem.
                      Typical commands are enable echo and display full
                      responses.

                      The following example for the Digital Scholar 2400
                      could be used to enable character echo:

                      ^tScholar 2400 Expert Mode^M^J^J^z^B^w&1,1^Z^w

                      o  ^tScholar 2400 Expert Mode^M^J^J^z-Displays the
                         message Scholar 2400 Expert Mode followed by a
                         carriage return and two line feeds

                      o  ^B-The control sequence Ctrl/B lets you enter
                         Scholar command mode

                      o  ^w-Wait 1/2 second for modem to respond

                      o  &1,1^Z-The Scholar 2400 commands that enable
                         echo for the characters you type in expert mode

                      o  ^w-Wait 1/2 second for modem to respond

        Connected     Use this option when you want to talk by
        from          telephone with someone at the remote site before
        handset:      establishing the connection.

                      It is sufficient with some modems to set the
                      Data/Talk switch on the modem to confirm a
                      successful connection. However, some new modems
                      no longer have this switch and it is necessary to
                      send a command to the modem to go off hook.

                      When you specify a command to confirm connected
                      from handset, each time you make a connection
                      using the handset you are prompted to press a key
                      when you hear the high-pitched carrier tone. When
                      you do this, the system will try for 5 seconds to
                      establish a connection.

                      The documentation for your modem explains how to
                      make connections using a handset. For example, the
                      Racal-Vadic 2400PA requires the following command:

                      ^E^M^w^G^M

                      o  ^E-The wakeup character for the Racal-Vadic
                         modem

                      o  ^M-Carriage return to complete command

                      o  ^w-Wait 1/2 second to give modem time to
                         respond

                      o  ^G-Go off hook

                      o  ^M-Carriage return to complete command

        Cancel dial   This is the control sequence that must be sent
        request:      to the modem when you want to stop the dialing
                      sequence after it has started.

                      Some modems continue to dial, even though the
                      system has effectively hung up. Your modem
                      documentation explains whether this is required.
                      If your modem resets when Data Terminal Ready is
                      set to OFF, then you need not define a sequence to
                      cancel the dial request.

                      For example, the control sequence to cancel a
                      dial request on the Digital Scholar 2400 is the
                      following:

                      ^B^w

                      o  ^B-The control sequence Ctrl/B tells the
                         Scholar 2400 to cancel the dial command

                      o  ^w-Wait 1/2 second for modem to respond

        Set up        Modems usually require some setup before they
        modem:        can operate with a computer. Some modems require
                      internal switches to be set; others can be set up
                      using commands. Some modems need to be set up each
                      time the power is turned on; others need to be set
                      up only once. Refer to Appendix C and your modem
                      documentation.

                      The setup commands you enter here are used each
                      time the system starts and whenever the option
                      Reset Communication Lines is selected.

                      When you define the setup command, it is
                      worthwhile to include the characters ^v at the
                      start of the command. This causes the interaction
                      between the modem and the system to be displayed
                      on the terminal. This is useful for confirming the
                      correct functioning of the modem.

                      The following example shows the command to set up
                      the Scholar 2400 modem:

                      ^v^B^w^r&1,0,0,2,0,0,3,1,1,1,0,0,1,1,0,1^M^w^r

                      o  ^v-Tells VAX PAC to display modem responses

                      o  ^B-The control sequence Ctrl/B lets you enter
                         Scholar command mode

                      o  ^w-Wait 1/2 second for modem to respond

                      o  ^r-Wait for modem response

                      o  ^w-Wait 1/2 second for modem to respond

                      o  ^r-Wait for modem response

        Reset modem:  When you break a connection to a remote system,
                      many modems immediately return to an idle state.
                      Some modems, however, require commands to return
                      them to the idle state. When a modem requires
                      reset commands, it can often take an extra 5
                      seconds to break a connection and continue normal
                      functions.

                      Use the reset command to display the modem
                      commands during computer dialing. Although this is
                      a good indication of the correct performance of
                      the modem, the modem will usually have to be reset
                      to a quiet mode of operation; otherwise you might
                      have problems with incoming calls.

                      The following example for the Digital Scholar
                      2400 could be used to disable character echo. The
                      Digital Scholar 2400 requires that you disable
                      echo and select abbreviated responses if you
                      want to support incoming calls. The characters
                      ^w specify a half-second wait to give the modem
                      time to respond.

                      The following example shows the command to set up
                      the Scholar 2400 modem:

                      ^B^w&1,0^Z^w

                      o  ^B-The control sequence Ctrl/B enters the
                         Scholar 2400 command mode

                      o  ^w-Wait 1/2 second for modem to respond

                      o  &1,0^Z-Tells the modem not to echo commands

        Use pulse     Many modems allow you to choose between tone
        dialing:      dialing and pulse/universal dialing. For some
                      modems you can select the option as part of the
                      modem setup, while others require that you specify
                      the option each time you dial.

                      You select either tone dialing or pulse dialing
                      when you set up your communication lines.

                      Enter the sequence of characters you must specify
                      in the modem commands when you want to specify
                      pulse dialing.

                      For example, the Digital DF112 and Digital Scholar
                      2400 modems require the letter P to indicate the
                      need for pulse dialing.

                      To use this feature, type the characters %P as
                      part of the modem commands for dialing or setup,
                      or in the phone number you specify when defining
                      a connection. VAX PAC replaces each occurrence of
                      %P with the value you enter here whenever pulse
                      dialing is specified for the communication line.

                      modems you can select the option as part of the
                      modem setup, while others require that you specify
                      tone or pulse each time you dial.

                      You select either tone dialing or pulse dialing
                      when you set up your communication lines.

                      Enter the sequence of characters you must specify
                      in the modem commands when you want to specify
                      tone dialing.

                      For example, the Digital DF112 and Digital Scholar
                      2400 modems require the letter T to indicate the
                      need for tone dialing.

                      To use this feature, type the characters %P as
                      part of the modem commands for dialing or setup
                      or in the phone number you specify when defining
                      a connection. VAX PAC replaces each occurrence
                      of %P with the value you enter here whenever tone
                      dialing is specified for the communication line.

        Wait for      Many modems with the autodial feature allow you
        dial tone:    to enter a character that denotes wait for a
                      secondary dial tone. Some long distance companies
                      require this feature. Enter the sequence of
                      characters you must specify in the dial command
                      when you want the modem to wait for a second dial
                      tone.

                      For example, the equal sign (=) is used by the
                      Digital Scholar 2400 to indicate wait for a
                      secondary dial tone. To use this feature, enter
                      the sequence %W in the phone number when defining
                      a connection.

                      When you call the remote system, each occurrence
                      of %W is replaced by the value you enter here.

              After you enter the information, press Do to set up your
              first modem.

              To cancel the information just entered, press Cancel.

              After you define a modem, its definitions are displayed
              along with all previously defined modems.

        2.5.4 XFR-Define Methods of File Transfer

              When VAX PAC is first installed, KERMIT is the only method
              of file transfer available. This means that when you want
              to transfer files between your system and a remote system,
              the remote system must also use the KERMIT file transfer
              method. If you intend to use XMODEM or some other file
              transfer method, use the XFR option to define the new
              file transfer method. When you select XFR, the screen in
              Figure 2-10 is displayed.

              If you want to use a file transfer method other than
              KERMIT (such as XMODEM), or a version of KERMIT other
              than the one supplied with VAX PAC, you must install the
              new file transfer method on your system.

              You can add, change, delete, or display file transfer
              methods. If no file transfer methods are defined when you
              select XFR from the Main menu, a screen for adding a new
              file transfer method is displayed. Thereafter, when you
              select the XFR option, a list of the file transfer methods
              you have already set up is displayed.

              Figure 2-11 is an example of the screen used for adding
              a file transfer method. Following the sample screen are
              explanations of each field.

        2.5.5 SRV-Define Remote File Transfer Servers

              The default file transfer server for Communications is
              KERMIT. If you intend to use XMODEM or some other file
              transfer server, use the SRV option to specify the new
              file transfer server.

              When you select SRV, the screen in Figure 2-12 is
              displayed.








        2-40 Managing VAX Public Access Communications

 







              Initially, KERMIT is the only file transfer server
              available.

              There are four ways of starting the KERMIT file transfer
              server: ASCII, Binary, Fixed, and Expert Mode.

              o  Use ASCII for simple text files. All versions of KERMIT
                 support ASCII, which is suitable for transferring files
                 with variable-length records between VMS systems or for
                 files containing special characters.

              o  Use Binary for transferring binary files from a
                 personal computer (such as CP/M COM files) that need
                 to be kept in a format that allows the file to be
                 returned without any change. Binary is not suitable
                 for transferring Record Management Services (RMS) files
                 between VMS systems.

              o  Use Fixed for transferring EXE files between VMS
                 systems. These files are stored as fixed-length, 512-
                 character records.

              o  Expert Mode allows you to use KERMIT commands
                 interactively. If you specify this mode, you see the
                 following prompt:

                 COMM$KERMIT>

                 Enter the HELP command for instructions on using KERMIT
                 in Expert Mode.

                 Press Ctrl/Z to return to VAX PAC.

              KERMIT: A File Transfer Protocol, a Digital Press book,
              offers more information on this subject.

              You can add, change, delete, or display remote file
              transfer servers. If no remote file transfer servers are
              defined when you select SRV from the Main menu, a screen
              for adding a new remote file transfer server is displayed.
              Thereafter, when you select the SRV option, a list of the
              remote file transfer servers you have already set up is
              displayed.

        2.5.6 KEY-Interrupt Key Procedures

              Interrupt key procedures allow you to suspend a connection
              to a remote system and perform another activity. When
              VAX PAC is installed, there are two interrupt procedures
              defined: Spawn DCL and A-to-Z Interrupt Menu.

              The VMS default interrupt procedure, Spawn DCL, returns
              you to the DCL command level (the $ prompt) after you
              press the Interrupt key. You can then enter DCL commands.
              When you have finished, log out and press Resume to
              continue using VAX PAC.

              On A-to-Z systems, the A-to-Z Interrupt Menu is displayed
              when you press the Interrupt key.

              You can make changes to the interrupt procedure by using
              the SYS-Set system defaults menu option.

              When you select the KEY option, a screen similar to
              Figure 2-14 is displayed.

              You can add, change, delete, or display interrupt
              procedures. If no interrupt procedures are defined when
              you select KEY from the Main menu, a screen for adding
              a new interrupt procedure is displayed. Thereafter, when
              you select the KEY option, VAX PAC displays a list of the
              interrupt procedures you have already set up.

              Figure 2-15 is an example of the screen used for adding

                                                             Modem Setup



              This appendix discusses how to set up modems for use with
              VAX PAC.

              The requirements for operation with VAX PAC might differ
              from the factory setup in two ways:

              o  The way the modem accepts and responds to commands from
                 the system

              o  The way in which certain modem control signals are
                 handled

              Section C.1 outlines setting up modems. Section C.2
              details the particular requirements for the following
              modems:

              o  Digital DFA01

              o  Digital DF03

              o  Digital DF112

              o  Digital Scholar 2400 (DF224)

              o  Digital Scholar Plus (DF242)

              o  Hayes Smart Modem 2400

              o  Hayes Smart Modem 1200

              o  Other modems supporting the AT command set

              See Appendix E for information on using a DTE_DF03, DTE_
              DF112, or DMCL dial module with a DMF32 controller.

        C.1 VAX PAC Modem Requirements

              The following sections contain general information on
              setting up a modem for use with VAX PAC.

        C.1.1 Guidelines for Using Modems with VAX PAC

              The following list contains guidelines for using a modem
              with VAX PAC:

              o  Set the modem character size to 8 data bits, 2 stop
                 bits, and no parity.

                 VAX PAC uses 8-bit, no parity when sending commands to
                 the modem.

              o  Set the modem for quiet operation for incoming calls.

                 Many modems send a response to the local system when an
                 incoming call is received. On a system with VAX PAC,
                 this can interfere with the system's ability to detect
                 the line speed for the incoming call.

                 On a VAX PAC system, the modem must be set up so this
                 feature is disabled. That is, the modem must not send
                 a message to the system when it receives an incoming
                 call.

              o  Enable autoanswer.

                 If you allow incoming calls to your system, you must
                 set up your modem to support autoanswer.

              o  Disable the speaker.

                 Some modems have loudspeakers for monitoring calls.
                 Unlike terminal operation, with VAX PAC the modem
                 is not usually located near the person making the
                 connection. In this case, there is little value in
                 enabling the modem's speaker.

        C.1.2 Modem Control Signals on the RS-232C Connector

              In general, VAX PAC requires that modems conform to the
              EIA RS-232C specification.

              Modems intended for operation with a terminal usually do
              not have the following signals correctly set for use with
              VAX PAC:

        C-2 Modem Setup

 






              o  DTR-VAX PAC uses Data Terminal Ready (DTR) to control
                 the modem. DTR is normally set to ON. VAX PAC switches
                 DTR to OFF for 5 seconds in order to end a connection.

                 Some modems are initially set up to operate as if DTR
                 were set to ON. This is incorrect for operation with
                 VAX PAC.

                 VAX PAC requires that the modem be set up so that the
                 modem returns to its initial state when DTR goes from
                 ON to OFF. Otherwise, VAX PAC will be unable to hang up
                 the phone, and you will continue to incur phone charges
                 after terminating the connection.

              o  DCD-Data Carrier Detect (RS-232C pin 8)

                 VAX PAC uses Data Carrier Detect (DCD) to determine the
                 state of the remote connection. When DCD is set to ON,
                 VAX PAC operates as if it were successfully connected
                 to a remote system. When DCD goes from ON to OFF, VAX
                 PAC operates as if the connection were lost.

                 Some modems initially are set up so that the modem
                 always sends the ON condition for DCD. This is
                 incorrect for operation with VAX PAC.

                 VAX PAC requires that the modem be set up so that the
                 modem sets DCD to ON only when data carrier is present.

        C.2 Modem-Specific Setup Requirements

              The following sections contain information on setting up
              specific modems for use with VAX PAC.

        C.2.1 Setup for Digital DFA01 Modem

              The factory-installed settings for the Digital DFA01
              modems are correct for operation with VAX PAC. The DFA01
              accepts Digital Modem Command Language (DMCL) and uses the
              DMCL dial module.

        C.2.2 Setup for Digital DF03 Modem

              The factory-installed settings for the Digital DF03
              series modems are correct for operation with VAX PAC.
              The factory-installed settings are shown in the DF03 Modem
              User Guide.

        C.2.3 Setup for Digital DF112 Modem

              The factory-installed settings for the Digital DF112
              series modems are correct for operation with VAX PAC.
              The factory-installed settings are shown in the DF112
              Modem Family User Guide.

        C.2.4 Setup for Scholar 2400 (Digital DF224) Modem

              The Digital Scholar 2400 modem (DF224) has switches inside

        C.2.5 Setup for Scholar Plus (Digital DF242) Modem

              The Digital Scholar Plus modem uses commands from the
              terminal to modify its operation. There are two command
              modes: the Digital Modem Command Language (DMCL) or the
              AT command processor, which is, as much as possible,
              compatible with the HAYES AT command set found in the
              Hayes Smart Modem 2400. This section deals only with the
              DMCL command mode. For information on the AT command set
              and the Scholar Plus, see the Scholar Plus User's Guide.

              You can use VAX PAC when setting up the modem, or you
              can connect the modem to the communication port on your
              terminal. Either way, the commands are the same.

              The factory-installed settings for the Digital Scholar
              Plus modems are correct for operation with VAX PAC. There
              is a four-position DIP switch mounted on the rear panel
              of the Scholar Plus modem; this switch is accessible from
              the outside. To select the Scholar Plus factory defaults,
              you must set the back panel option switches to the correct
              setting (see Table C-3) and turn power off and then on to
              cause factory defaults for all software-settable options
              to be read.

                ________________________Note  ________________________

                Option switches and jumpers on the Scholar Plus
                modem are read during the following operations:

                o  Power-up reset

                o  A mode switch between AT and DMCL, or between
                   DMCL and AT

                o  An ATZ command in AT mode

                o  An ENABLE SELF-TEST command in DMCL mode

                _____________________________________________________

              The back panel option switches should be set as shown in
              Table C-3.

              The following procedure describes how to use VAX PAC to
              set up the Scholar Plus modem.

                ________________________Note  ________________________

                While performing this procedure, you may receive an
                error message from the modem (for example, "Error:1
                Invalid Syntax"). If you receive such an error
                message, press Ctrl/B to wake up the modem. The
                modem should respond with a Ready message before you
                can give it another command.

                _____________________________________________________

              1. Set your back panel modem switches as described in
                 Table C-3.

              2. Set up the communication line using the SET option on
                 the VAX PAC Manager's Main menu.

              3. After you have set up the communication line, select
                 the CON option from the Manager's Main menu.

              4. Select the Manual connection option from the Select a
                 Connection menu.

              5. Use the left and right arrow keys to select the
                 following fields on the Manual Connection menu:

                 Dial method:            <Use expert dialing mode>
                 Communication line:     <Digital SCHOLAR PLUS line>

              6. Press the Do key to connect to the modem. You should
                 get the "You are now connected . . . " message followed
                 by:

                 DMCL: Expert Mode

                 Ready

              7. Disable the Scholar Plus speaker by issuing the
                 following command to the modem:

                 SET P12:0/OPE

              8. Change ring to answer on 2 to 1 with the following
                 command:

                 SET P14:1/OPE

              9. The default for Local Baud Rate is 2400 bps. Optionally,
                 you may want to use the following command to change the
                 Local Baud Rate:

                 SET P4:x/SBU

                 Where x is:

                    0 for 1200 bps
                    1 for 2400 bps
                    2 for 4800 bps
                    3 for 9600 bps

                ________________________Note  ________________________

                At this point you can set other Scholar Plus
                parameters. See the Scholar Plus User's Guide for
                a complete list of settable parameters.

                _____________________________________________________

              10.After you have set the modem setup parameters, issue
                 the WRITE command to the modem to save them:

                 WRITE

              11.Finally, turn off SW1 on the back panel of the modem
                 and power on the modem. Unless you redo the above
                 procedure, change a setting, and issue a WRITE command,
                 the modem will always power up with factory default
                 parameters and the changes you have made.

        C.2.6 Setup for Hayes Smart Modem 2400

              The Hayes Smart Modem 2400 uses commands from the terminal
              to modify its operation. These commands are often referred
              to as the AT command set.

              You can use VAX PAC when setting up the modem, or you
              can connect the modem to the communication port on your
              terminal. Either way, the commands are the same.

              In order to use VAX PAC to set up the modem, you must
              first set up the communication line using the SET option
              on the VAX PAC Manager's Main menu. Once you have set up
              the communication line, choose the CON option from the
              Manager's Main menu and then select the Manual connection
              option. Finally, choose Expert dial mode. This allows you
              to enter modem commands as if your terminal were connected
              directly to the modem.

              The commands listed in Table C-4 are used to set up
              your Hayes Smart Modem 2400 and save the settings as the
              default configuration. Press Return after each command.

        C.2.8 Other Modems Supporting the AT Command Set

              Many modems offer compatibility with the AT command set
              used by Hayes. Be aware that implementations of the AT
              command set vary among manufacturers. Some are closely
              compatible with the Hayes Smart Modem 2400; others are
              either closely compatible with the Hayes Smart Modem 1200
              or offer a subset of the AT command set. Read your modem
              documentation before proceeding with the modem setup.

              Some modems lose their current settings when the power
              supply is interrupted.

                                              Modem Commands for VAX PAC



              VAX PAC uses codes for building modem commands. These
              allow you to send special characters and to monitor the
              progress of each command. There are three types of codes:

              o  Codes used for accessing VAX PAC fields

              o  Codes used for sending special characters

              o  Command codes that control VAX PAC

              This appendix explains and lists these codes.

        D.1 Codes for Accessing VAX PAC Fields

              You need to access values for certain VAX PAC fields in
              the modem dial command. You do this with special codes
              in the dial command. Each code is replaced by the current
              value for the field.

                                        useful for display purposes.
                                        For example, to display the
                                        following message:

              %P          Tone/Pulse    The value for this field is
                          dialing       determined by the dialing
                                        method you specify for the
                                        communication line. Use this
                                        in the dial command to specify
                                        tone/pulse dialing.

                                        Most dial commands contain the
                                        sequence %P%D.

        D.2 Codes for Control Characters

              You can send any character to the modem. However, some
              characters require a code in order to be recognized by VAX
              PAC. The codes for specifying control characters can be
              used in all modem commands.

              The most commonly used control characters can be
              represented using alphabetic characters. Codes used to
              represent control characters are always in uppercase.

              Sometimes you might need to send control characters
              that cannot be represented by an alphabetic character.
              In this case, you will have to use the numeric codes.
              These are the octal values and not the decimal values for
              the control character. (Octal is a number that is based
              on 8 rather than on 10.) Octal codes are often used to
              represent characters in the ASCII character set.

              VAX PAC uses the following codes to represent control
              characters.

              o  ^A-^Z: character codes 1-26 (decimal)

              o  ^001-^377 (octal): character codes 1-255 (decimal)

              If you need to use the control character NUL, you should
              use the VAX PAC command ^a. (Section D.3 explains the
              codes used for VAX PAC commands.)

              The codes ^201-^232 (decimal 129-154) must be preceded
              by the VAX PAC command ^q, except when used in the dial
              command for the DMCL dial module.

              Table D-2 lists the codes used by VAX PAC for sending the
              most commonly used control characters.

        D.3 Codes for VAX PAC Commands

              In addition to sending characters to the modem, you might
              sometimes need to perform special functions. To do this,
              use VAX PAC commands. The codes for VAX PAC commands
              always use lowercase letters.


        D-4 Modem Commands for VAX PAC

 






              You can use the codes for VAX PAC fields and the control
              characters in all modem commands. However, under some
              circumstances, the codes for VAX PAC commands would be
              interpreted incorrectly.

              The dial commands for DMCL, DTE_DF03, and DTE_DF112 do
              not support VAX PAC commands. If you use them in the dial
              commands for these dial modules, they send 8-bit control
              characters that might give you an error.

              VAX PAC command codes are acceptable in all other modem
              commands, as well as in the dial command for the GENERIC
              dial module.

                                 Using the DMF32 Controller with VAX PAC



              If you plan to attach a modem to one of the two modem
              ports (ports 0 and 1) on a DMF32 controller on your VAX
              system, you should be aware that the DMF32 does not allow
              messages from the modem to be received until it senses
              carrier from the modem. This means that any message
              sent by the modem while dialing a remote system is not
              returned.

              Because of this limitation, the following restrictions
              apply when using DMF32 controllers:

              o  While in Expert Mode dialing, VAX PAC will display
                 only the characters that you enter from the keyboard.
                 Because the DMF32 does not display the modem responses,
                 you will not see the messages from the modem documented
                 in your modem documentation.

                 Also, note that the connection is set for local echo
                 and automatic newline until the connection has been
                 established.

              o  The DTE_DF03, DTE_DF112, and DMCL dial modules rely
                 on messages from the modem to determine a successful
                 connection. Because these messages are not returned,
                 you cannot select these dial modules for communication
                 lines using the DMF32 controller.

              o  You should use the GENERIC dialer when using a DMF32.
                 Note that the following modem commands work differently
                 when you dial out using a DMF32. This allows existing
                 GENERIC modem definitions to work with the DMF32.
