   Format

     TN3270  [ host ]

             [ /CHARACTER_SET=file ]

             [ /KEY_DEFINITIONS=file ]

             [ /NATIONAL_CHARACTERS=char_set ]

             [ /NOINTERACTIVE ]

2  Parameters
 

host

   Optional.

   Remote host to which you want to connect. Specify one:

   o  Host name

   o  IP address
 

2  Qualifiers
 

/CHARACTER_SET

      /CHARACTER_SET=file

   Optional. Default: ORIGINAL.

   File with the EBCDIC-to-DMCS (DIGITAL Multinational Character
   Set) and the DMCS-to-EBCDIC translation tables.

   If you omit this qualifier, TN3270:

   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 US 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. (See
      the Compaq TCP/IP Services for OpenVMS Management manual for
      information about the EBCDIC / DMCS translation tables.)

                                     NOTE

         To reset the default, do not abbreviate ORIGINAL.
 

/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.
 

/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 DIGITAL
   terminal is configured. Specify one of the following:

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

/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.
 

/PORT

      /PORT=n

   Optional. Default: 23.

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

/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).
 

/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 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.
 

/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
 

2  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.
