    PROBLEMS RESOLVED:

    - FTSII unable to receive sequential files from the host.  Error message
      on PC reports:  "Unable to transfer file.  Must be sequential or
      partitioned."  (PR#B41001)

    - When trying to receive a file from the host, user gets the message
      "Warning - unable to restore TSO Profile".  The FTSII software then
      aborts to DOS.  The host is running under "TSS" which is supposed to be
      TSO compatible.  (PR#B41003)

    - Cannot transfer file when under TSO/E release 3.  User receives error
      message "Unable to transfer file - logical record length greater than
      255."

    - During file transfer, records are dropped and data is garbled.  Host is
      operating under TSO-E1 release 4.0. (PR#B41012)

    - At the beginning of a transfer, FTS-II displays the message
      "Initializing Host", at which point the PC hangs.  The host is running
      under DOS VS/E, CICS version 1.6.  (PR#B41013)

    - No records transfer when downloading a TSO dataset.  The FTS-II
      software initializes and appears to open the correct data set, but no
      information is actually downloaded from the host.  (PR#B41014)

    - The system with the emulation software is connected to a "Stratus
      Passthrough Computer" located between it and the controller.  Emulation
      operates fine, but when attempting a file transfer, the error message
      "Not at TSO command level" is generated by the FTS-II software.
      (PR#B41015)

NOTE:  For a complete list of all changes made to the ENTRY and SEND/RECEIVE
       file transfer software please refer to the file "READ.ME" on the
       distribution diskettes.
