/sys$common/syshlp/helplib.hlb TCPIP Services, TELNET, TN3270 Troubleshooting  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    During a TELNET session in which you have invoked TN3270, you
    might experience the following problems:

    Problem

    o  The keyboard keys do not work properly.

    o  Messages, such as the status line messages, do not appear in
       reverse video.

    o  You receive a message indicating that your terminal is an
       unsupported model.

       You cannot use TN3270 on a VT131 model terminal that is
       running in block mode.

    Solution for a VT100-Series Terminal

    Use Set-Up mode to verify that your terminal is in ANSI mode.
    Issue the following command:

    $ SET TERMINAL /INQUIRE
    Solution for a VT200-Series Terminal or a Terminal Connected to
    Either a DIGITAL Personal Computer or a Workstation

    1. Use Set-Up mode to verify that your terminal is:

       o  In ANSI mode

       o  Set to VT100 or VT200 emulation mode

    2. Check the Communications Menu:

       The terminal communications line must be set for 8-bit
       characters. To check, issue the following command:

       $ SET TERMINAL /INQUIRE

    Solution for a Terminal with a National Language Keyboard

    Ensure that your terminal is set up to correspond to your
    keyboard.

    Problem

    You receive a message indicating that the screen size (or the
    alternate screen size) specified by the remote host is too big.
    Solution

    Use Set-Up mode to change to a valid screen size.

    Problem

    You try to use the RECORD or PLAY function, but you get an error
    message indicating that you have a bad key sequence file.
    Solution

    The file that stores the recorded key sequence is incompatible
    with the current version of the software or is corrupted.

    Ask your system manager to do either of the following:

    o  Correct TCPIP$RECSEQ.DAT in your SYS$LOGIN directory.

    o  Delete TCPIP$RECSEQ.DAT.

       If the system manager must delete this file, rerecord all the
       key sequences you had stored on the PF keys.
