          Dear Customer:

          The VMS/SNA Version 2.1 software is a limited maintenance re-
          lease. It includes problem fixes and support for new processors.
          It does not contain any major enhancements or changes. The user
          documentation has not been updated since VMS/SNA Version 2.0.

          However, changes pertaining to the documentation can be found in
          the VMS/SNA Version 2.1 Release Notes contained in this kit.

          Please take a few moments to read the following information
          about your VMS/SNA Version 2.1 software distribution kit.

          o  The Bill of Materials specifies the number and contents of
             the distribution kit. Check to see that all items are in the
             kit. If any items are missing or damaged, contact Digital
             Equipment Corporation.

          o  Make sure you have installed Version 5.4 of the VMS operating
             system.

          o  If you are planning to use X.25 switched virtual circuits
             for communication between the VMS/SNA system and the IBM
             host system, install and configure the VAX Packetnet System
             Interface (P.S.I.) software, Version 4.3.

          o  Contact your Digital service representative to install the
             VAX communications hardware device you intend to use with the
             VMS/SNA software (if not already installed). See the Software
             Product Description for a list of devices supported on your
             VAX processor.

          o  Read VMS/SNA Installation before installing the software.
             VMS/SNA software configuration is dependent upon your site-
             specific IBM configuration; you should have access to the IBM
             configuration details before you begin the VMS/SNA software
             installation.

          o  VMS/SNA software uses specific external communications hard-
             ware (such as modems) that should already be in place. In
             addition, the installer needs to know the operational config-
             uration of the communications line (for example, full-duplex
             or half-duplex). These requirements are explained in VMS/SNA
             Installation.

          The VMS/SNA Version 2.1 Release Notes are on line as part of
          the software distribution kit. These release notes provide
          software updates not included in the manual set. To access the
          release notes during the installation, specify OPTIONS N in the
          VMSINSTAL procedure:

               $ @SYS$UPDATE:VMSINSTAL SNAVMS021 device OPTIONS N

          The OPTIONS N keyword allows you to indicate whether you
          want the release notes displayed, printed, or both. You can
          also specify the print queue name. Whether or not you spec-
          ify OPTIONS N, the release notes are copied to the file
          SYS$HELP:SNAVMS$021.RELEASE_NOTES. Digital Equipment Corporation
          recommends saving the release notes for the previous version of
          VMS/SNA, if they are present.
