Starts a TELNET session that runs TN3270 and does one of the
following:
o Displays the TELNET prompt.
o Establishes a connection to a remote host.
For help with individual TELNET commands, enter the following
command:
$ TN3270
TELNET> HELP
Format
TN3270 [ host ]
[ /CHARACTER_SET=file ]
[ /KEY_DEFINITIONS=file ]
[ /NATIONAL_CHARACTERS=char_set ]
[ /NOINTERACTIVE ]
[ /PORT=n ]
[ /PRINTER=file ]
[ /STATUS=state ]
[ /TERMINAL_TYPE=IBM-3278-n ]
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.
