tn5250rc: tn5250 and lp5250d configuration file

Command to display tn5250rc manual in Linux: $ man 5 tn5250rc

NAME

tn5250rc - tn5250 and lp5250d configuration file

DESCRIPTION

The tn5250rc file contains groups of options for tn5250 and lp5250d. When a hostname is passed to one of these programs, the named group is looked up in tn5250rc, and any options given in that group are processed.

If a named group is found, and defines a host option, that option specifies the server. Otherwise, the host parameter to the program is used.

A group of options looks like this:

groupname {
  +boolean
  option=value
  ...
}

Each group of options starts with the group name, followed by a left brace (curly bracket) character. Following lines should have one option on each line. The last line of the group has a single right brace.

The global tn5250rc file may be overridden by the user's ~/.tn5250rc file.

OPTIONS

The options given here may be used inside a section of the configuration file, or on the tn5250 or lp5250d command line. Most options take the form OPTION=VALUE. Options listed with a leading +/- can be either turned on (+OPTION) or off (-OPTION).

Common Options

These options apply to both printer and display emulation sessions.

host=URL: Set the host to connect to. The URL is of the form [PROTOCOL:]HOSTNAME[:PORT]. The default protocol, if not supplied, is tn5250. See Protocols below for descriptions of the available protocols.
map=CCSID: Set the translation table between ASCII and EBCDIC. This should match the CCSID of the interactive job. The default is 37. See Translation Maps below for more information.
env.DEVNAME=NAME: Set the device name for the AS/400 to assign to the 5250 session. This should be up to ten characters long and consist of only letters and numbers. It will be converted to uppercase and used as the name of the 5250-compatible device on the AS/400. There may only be one session active with any given name at one time.
trace=TRACEFILE: Log all actions to TRACEFILE. This file will get very large, and may contain sensitive information such as the password used to log in.
+/-ssl_verify_server: If set, then verify that the server's certificate was issued by a CA in the file given by the ssl_ca_file option. If the certificate's issuer cannot be verified, do not connect to the server.
ssl_ca_file=CAFILE: Specify the file containing the certificate for the CA that issued the server's certificate. If the server certificate is self-signed, CAFILE should contain the certificate displayed by the Digital Certificate Manager option Copy and paste certificate.
ssl_cert_file=CERTFILE: Specify the file containing the personal certificate, in PEM format. This must be a certificate associated with your user profile on the AS/400 by DCM.
ssl_pem_pass=PASSWORD: If the personal certificate given by ssl_cert_file is password protected, the password may be given here to bypass the password prompt.

Display Options

These options are specific to tn5250 and xt5250.

+/-underscores: Force or disable the use of underscore characters instead of the underline attribute, for terminals that do not support underlining but where tn5250 does not work this out itself.
+/-ruler: Turn the ruler feature on or off. When enabled, the row and column of the cursor will be highlighted.
env.TERM=MODEL: Set the terminal model name for the emulation session to use. The default depends on whether the terminal supports colour, and whether it is large enough to support the large terminal size. See Display Types below for valid model names.
: The default model emulated is an IBM-3179-2, a 24x80 colour terminal.
font_80=FONT: If tn5250 is running in an xterm, sets the font to change to when the terminal is in 80 column mode. This should be a valid X font name, such as can be chosen with xfontsel.
font_132=FONT: If the emulated terminal has a size of 27x132, set the font to use in 132 column mode, as for the font_80 option.
beep_command=COMMAND: If present, will run the supplied command instead of using the terminal beep.
+/-uninhibited: If enabled, automatically resets the input inhibited state when cursor movement keys or function keys are pressed. The default is disabled.
env.VARIABLE=VALUE: Set any other environment variables controlling the terminal session. A list of relevant variables is given in section 5 of RFC2877.

Printer Options

outputcommand=COMMAND: Set the command that will be run to receive printer output. The default command is `scs2ascii |lpr'.
env.IBMMFRTYPMDL=NAME: Set the name of the host print transform description to use on the AS/400. This is the same as the MFRTYPMDL parameter on the CRTDEVPRT command. See the CL Reference or the online help for a list of valid values.
env.VARIABLE=VALUE: Set any other environment variables controlling the printer session. A list of relevant variables is given in section 7 of RFC2877. More generally, the variables are the parameters of the CRTDEVPRT command, with a prefix of IBM.

OPTION VALUES

Protocols

The supported protocols for the emulation session are listed below.

telnet: Connect to the AS/400 using a normal unencrypted telnet connection. tn5250 is an alias for telnet.
ssl: Connect securely using an encrypted SSL session. This option is only available if tn5250 was compiled with SSL support.
debug: Instead of connecting to a server, replay the trace generated by the trace option. The path to the trace file should be given instead of the hostname.

Translation Maps

CCSIDs on the AS/400 are listed in Appendix G of IBM manual SC41-5101-01, AS/400 National Language Support. This manual is available on the web at <http://publib.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/QB3AWC01/G.2>.

Currently recognised values for the translation map are: 37, 256, 273, 277, 278, 280, 284, 285, 290, 297, 420, 424, 500, 870, 871, 875, 880, 905, and 1026. Most of these are translated to ISO-8859-1, also known as Latin 1. Some of them contain characters only present in another encoding, which is used instead. The valid CCSID values, and the Unix encoding used, are listed below.

CCSID	Unix encoding	Description

		Portugal, Brazil, Australia,
		New Zealand
256	ISO-8859-1	Netherlands
273	ISO-8859-1	Austria, Germany
277	ISO-8859-1	Denmark, Norway
278	ISO-8859-1	Finland, Sweden
280	ISO-8859-1	Italy
284	ISO-8859-1	Spanish, Latin America
285	ISO-8859-1	United Kingdom
290	JIS_X0201	Katakana Extended
297	ISO-8859-1	France
420	ISO-8859-6	Arabic
424	ISO-8859-8	Hebrew
500	ISO-8859-1	Belgium, Canada, Switzerland
870	ISO-8859-2	Eastern Europe
871	ISO-8859-1	Iceland
875	ISO-8859-7	Greek
880	ISO-8859-5	Cyrillic
905	ISO-8859-3	Turkey - Latin3
1026	ISO-8859-9	Turkey - Latin5

If possible, configure your terminal to use the appropriate encoding if your AS/400 uses any of these CCSIDs.

Display Types

The following values are valid for the env.TERM option.

Name	Description

IBM-3180-2	27x132 monochrome
IBM-3196-A1	24x80 monochrome
IBM-3477-FC	27x132 color
IBM-3477-FG	27x132 monochrome

EXAMPLES

Define a connection named dsp01 that connects to the machine iseries.example.com, using the German CCSID, a 132 column terminal, and printing underscore characters instead of using underlines.

disp01 {
  host = iseries.example.com
  map = 273
  env.TERM = IBM-3477-FC
  +underscores
}

Define a printer connection, using host print transform to produce PCL output for an HP Laserjet compatible printer.

print01 {
  host = iseries.example.com
  env.DEVNAME = HPLJ01
  env.IBMMFRTYPMDL = *HP4
}

Define a secure SSL session, checking the server's certificate against the CA certificare stored in cacert.pem, and using the client certificate in jbloggs.pem to sign on automatically.

secure01 {
  host = iseries.example.com
  +ssl_verify_server
  ssl_ca_file = cacert.pem
  ssl_cert_file = jbloggs.pem
}
