          1. INTRO

          The Digi UnixWare RealPort (ncxa) driver makes the ports on
          Digi units appear as though they are local UnixWare tty
          devices directly attached to the computer.


          2. SUPPORTED PRODUCTS

              PortServer
              PortServer II
                  PortServer TS
                  Digi One RealPort Device Server
              Etherlite (with Realport firmware)


          3. ENHANCEMENTS

          The driver now supports new RealPort units which are listed
          above, and the fastbaud rates are now changed to support
          rates up to 921600. Note that older units may not support
          the highest baud rates. Here is the new fastbaud table:
          0 - 0
          50 - 57600
          75 - 76800
          110 - 115200
          134 - 131657
          150 - 153600
          200 - 230400
          300 - 460800
          600 - 921600
          1200 - N/A



                                     - 1 -






          1800 - N/A
          2400 - 2400
          4800 - 4800
          9600 - 9600
          19200 - 19200
          38400 - 38400
          Please note that if you select a baud rate the unit cannot
          handle, you will not get an error message.

          4. BUG FIXES

          Spurious RWIN updates are no longer made.


          5. KNOWN LIMITATIONS

          There is no way to convert the configuration from the
          previous UnixWare RealPort driver to the new driver.

          If you are creating a response script for multiple
          installations, do not choose to run ncxa_config during the
          installation process.  Responses to ncxa_config will not be
          saved in the response script.  After installation, copy
          /etc/ncxa.conf to each machine or run ncxa_config on each
          machine.

          The alternate start and stop characters are not "sticky",
          the port must be kept open to retain these settings.


          6. COMMENTS

          Be sure to install all relevant UnixWare patches.  For
          example, an unpatched UnixWare 7.1.0 system will eventually
          crash if RealPorts are opened and closed repeatedly.
          UnixWare patches available from SCO fix this problem.

          Unit ports used exclusively for RealPort use should be
          configured as type "dev=prn" or "dev=rp".  See the hardware
          documentation for more information on this.


          7. BASIC INSTALLATION

          If you have the file 40001130_H.bin on disk, as root run
              pkgadd -d /FULL_PATH_TO_DIRECTORY/40001130_H.bin ncxa
          where you must replace FULL_PATH_TO_DIRECTORY with the full
          path of the directory containing 40001130_H.bin.

          If you have the file 40001130_H.bin on a floppy, as root run
              pkgadd -d diskette1 ncxa

          You can also install the driver by running scoadmin.  First
          choose Software_Management, then Application Installer.  To
          install from a file choose Install From: Other, then enter
          the full pathname to 40001130_H.bin.  To install from a



                                     - 2 -






          floppy choose Install From: Disk_A, then click on ncxa, and
          finally click on Install.

          You must run realport_config to configure the RealPorts for
          your units.  You will need to know the hostname or IP
          address of each unit, how many ports it has, and what device
          names you want to use for those ports.  The realport_config
          program will suggest defaults for port names and it has a
          help option for more information.  You can run
          realport_config during the installation, or after it
          completes.

          You can change the configuration at anytime by running
              realport_config


          8. GETTING TECHNICAL SUPPORT

          Read the the Digi UnixWare RealPort manual, the readme.txt
          file in /opt/ncxa, the man pages, and the relevant UnixWare
          documentation.  The RealPort manual has installation and
          configuration instructions and a trouble shooting section
          which might be helpful.  The readme.txt file and man pages
          have technical details about this driver.

          9. HISTORY

          Ver 3.0.3

          The Unixware driver has been redesigned and rewritten for
          better performance and capablities.  Improved configuration
          utilities allows units to be added and removed dynamically.

          Man pages for the driver, daemon, and utilities have been
          added.
