This release includes all problem fixes and enhancements of all previous
releases, plus the following:

    PROBLEMS RESOLVED:

    - When using FTS-II software with DFT,  error message "NOT AT TSO COMMAND
      LEVEL" is displayed. This is due to incorrect translation of two Device
      Buffer codes in the international keyboard files.  Also, with this
      version the international keyboard files are included with DFT
      software.

    - Keypad number "5" key did not operate properly.  When the keyboard was
      configured as "enhanced", the "5" key would trigger a keyboard macro
      even though the numlock key was enabled. (PR#A58002)

    - DFT would not allow a printer session to be enabled without any display
      sessions also being configured. (PR#A58004)

    - With the Coax II board installed in a Unisys 12MHz AT, the DFT software
      would not establish connection with the host.  The controller the Coax
      II board was connected to was a Telex 274.  (PR#A58005)

    - The DFT software failed to load when there were more than 11 entries in
      the AUTOEXEC.BAT file.  When attempting to execute the 3270DCP.EXE
      program, the error "Read File Failed" would be generated, and the DFT
      emulation aborts.  (PR#A58006)

    ENHANCEMENTS:

    - NON-SNA channel attachment and remote attachment support is included
      with this release.

    - HP Laserjet support is now supported.

    - Support of EAB and 3279 models 3, 4, and 5 support for FTS-II has been
      added.

    - Translation of international EBCDIC to ASCII printer characters now
      supported.

Production Release 1.0         Available April, 1988

Part Number:  910232-001       5.25 inch diskette 1 of 3
              910232-002       5 25 inch diskette 2 of 3
              910232-003       5.25 inch diskette 3 of 3

              910232-031       3.50 inch diskette 1 of 1

This software emulates up to five IBM 3278/79/87 display and printer stations
using DFT SNA protocol over coaxial lines to an IBM mainframe.  The product
also supports IBM (CUT and DFT) and IRMA (CUT) 3278/79 emulation products.
This version does not support NON-SNA (BSC and channel-attached NON-SNA)
protocol.
