Includes all problem fixes and enhancements of all previous versions, plus
the following:

    PROBLEMS RESOLVED:

    - The 3270CNF.EXE configuration program would not allow subsequent
      changes to be made to the SNA II configuration once changes had been
      made to the "Printer entry strings" in the configuration program.  The
      system would lock up if attempting to use a configuration file made
      after these printer strings were once modified.  (PR#B54001)

    - The password for SNA II software would sometimes be visible on the
      screen as it was entered, even though it should be invisible.
      (PR#B54002)

    - Print data sent to a printer attached to a system running SNA II
      emulation would be corrupted if the data was 132 columns wide.  Spaces
      embedded in the data would be dropped by the emulation software causing
      forms to be misaligned. (PR#B54003)

    - "Pan-Link" software from Pan Sophic would not operate with SNA II.
      Executing this software while under emulation would cause the system to
      lock up.  (PR#B54004)

    - When using the "Enhanced" keyboard file with SNA II, the number pad "5"
      key would not function consistently. (PR#B54005)

    - While operating under emulation, the keyboard would lock up if the
      "END" key were pressed.  The host would be operating under CICS, and
      the terminal screen would be clear. (PR#B54008)

    - Emulation software would not receive a full screen of text from the
      host (operating under CICS, with NCP 4.1). (PR#B54009)

    - When attempting to run the "3270SCP.EXE" program with SNA II installed
      in an IBM PS/2 Model 55SX, the error messages "Unable to determine
      system type" and "Initialization aborted" would be generated.
      (PR#B65001)

    ENHANCEMENTS:

    - Beginning with this version of the software, only one set of software
      is required to support either the standard bus or micro channel
      versions of the product.  Previously, each adapter had it's own version
      of the SNA II software.
