    For help with individual TELNET commands, enter the following
    command:

    $ TN3270
    TELNET> HELP

    Format

1  –  Parameters

 host

    Optional.

    Remote host to which you want to connect. Specify one of the
    following:

    o  Host name

    o  IP address

2  –  Qualifiers

2.1    /CHARACTER_SET

       /CHARACTER_SET=file

    Optional. Default: ORIGINAL.

    File with the EBCDIC-to-DMCS and the DMCS-to-EBCDIC translation
    tables.

    If you omit this qualifier, TN3270 does the following:

    o  Uses the translation table named by the default file
       SYS$LIBRARY:TN3270DEF.TBL, if your system manager has created
       it.

    o  Defaults to its own translation table if TN3270DEF.TBL does
       not exist. The default table maps the EBCDIC set to the
       equivalent DMCS characters.

       If none of these translation tables meets your needs, the
       system manager can generate a new translation table. (For
       information about the EBCDIC-to-DMCS translation tables, refer
       to the HP TCP/IP Services for OpenVMS Management manual.)

                                      NOTE

          To reset the default, do not abbreviate ORIGINAL.

2.2    /KEY_DEFINITIONS

       /KEY_DEFINITIONS=file

    Optional. Default: default keyboard layout.

    Keyboard definition file you created to redefine how the TN3270
    key functions correspond to your keyboard layout. This file holds
    the definitions for alternative keyboard mapping.

2.3    /NATIONAL_CHARACTERS

       /NATIONAL_CHARACTERS=character_set

    Optional. Defaults: For 8-bit terminals: MULTINATIONAL
    For 7-bit terminals: US_ASCII.

    National Replacement Character Set (NRCS) for which your terminal
    is configured. Specify one of the following:

    Canadian          MULTINATIONAL
    Dutch             Norwegian
    Finnish           Spanish
    French            Swedish
    German            Swiss
    Italian           UK_ASCII
    Japanese          US_ASCII

2.4    /NOINTERACTIVE

    Optional. Default: TELNET command mode.

    Disables the capability of using the escape character to leave
    a session and return to the TN3270 prompt. This option is useful
    when the TN3270 command is referenced in a command procedure in a
    captive account.

2.5    /PORT

       /PORT=n

    Optional. Default: 23.

    Remote port to which you want your TELNET/TN3270 process to
    connect. Use this qualifier only if you are connecting to a host
    that does not use the standard TELNET port.

2.6    /PRINTER

       /PRINTER=file

    Optional. Default: TN3270PRINT.LIS.

    File that records your screen's contents when you use the PRINT
    function.

    Directs printer output to either a file or a spooled printer (not
    a physical printer or terminal).

2.7    /STATUS

       /STATUS=state

    Optional. Default: AUTOMATIC.

    Determines how the status line operates during your session.
    Specify one of the following:

    AUTOMATIC       Status line is displayed.

                    The status line is disabled automatically if the
                    remote host writes data to the area under the
                    status line, or if you type in that space.

                    The status line is restored automatically when
                    the data is erased.
    ON              Status line is always displayed.
    OFF             Status line is not displayed.

    To toggle between ON and OFF, invoke the STATUS function.

2.8    /TERMINAL_TYPE

       /TERMINAL_TYPE=IBM-3278-n

    Optional. Default: IBM-3278-2.

    IBM terminal to emulate. Enter the full specification for one of
    the following:

    o  IBM-3278-2

    o  IBM-3278-3

    o  IBM-3278-4

    o  IBM-3278-5

3  –  Examples

    1.$ TN3270 MYCOM

      Establishes a TELNET connection to remote host MYCOM. By
      default, the physical terminal functions as an IBM-3278-2 model
      terminal.

    2.$ TN3270 130.180.5.5 /TERMINAL_TYPE=IBM-3278-3 -
      _$ /KEY_DEFINITIONS=MY_NUMPAD.FIL

      Establishes a TELNET connection to the host at IP address
      130.180.5.5. The terminal functions as if it were an IBM-3278-3
      model terminal, and it uses the customized keyboard definition
      file MY_NUMPAD.FIL.

    3.$ TN3270 UCOM 31 /TERMINAL_TYPE=IBM-3278-5 /PRINTER=LOG

      Establishes a TELNET connection to remote host ucom:

      o  The connection is at port 31 on ucom.

      o  The terminal is functioning as if it were an IBM-3278-5
         model terminal.

      o  During the session at ucom, using the PRINT function records
         the screen's contents in a file named LOG.LIS.
