tn5250rc - tn5250 and lp5250d configuration file
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
If a named group is found, and defines a host option, that option
specifies the server. Otherwise, the host parameter to the program is
A group of options looks like this:
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
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).
These options apply to both printer and display emulation sessions.
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.
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.
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.
Log all actions to TRACEFILE. This file will get very large,
and may contain sensitive information such as the password used
to log in.
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
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
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.
If the personal certificate given by ssl_cert_file is password
protected, the password may be given here to bypass the password
These options are specific to tn5250 and xt5250.
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.
Turn the ruler feature on or off. When enabled, the row and
column of the cursor will be highlighted.
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
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.
If the emulated terminal has a size of 27x132, set the font to
use in 132 column mode, as for the font_80 option.
Set any other environment variables controlling the terminal
session. A list of relevant variables is given in section 5 of
Set the command that will be run to receive printer output. The
default command is ‘scs2ascii |lpr’.
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.
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.
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.
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
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.

If possible, configure your terminal to use the appropriate encoding if
your AS/400 uses any of these CCSIDs.
The following values are valid for the env.TERM option.
IBM-3179-2 24x80 color
