tset(1) — USER COMMANDS

NAME

tset − provide information for setting terminal modes

SYNOPSIS

tset [options] [type]

DESCRIPTION

tset allows the user to set a terminal’s ERASE and KILL characters, and define the terminal’s type and capabilities by creating values for the TERM and TERMCAP environment variables. If a type is given with the -s option, tset creates information for a terminal of the specified type. The type may be any type given in /usr/share/lib/termcap. If the type is not specified with the -s option, tset creates information for a terminal of the type defined by the value of the environment variable, TERM unless the -h or -m option is given. If the TERM variable is undefined, tset looks in /usr/share/lib/termcap for the appropriate information. If these options are used, tset searches the /etc/ttytype file for the terminal type corresponding to the current serial port; it then creates information for a terminal based on this type. If the serial port is not found in /etc/ttytype, the terminal type is set to dumb.

tset displays the created information on the standard output. The information is in a form that can be used to set the current environment variables. The exact form depends on the login shell from which tset was invoked. The examples below illustrate how to use this information to change the variables.

The following options are valid:

-e[c] Sets the ERASE character to [c] on all terminals. The default setting is BACKSPACE, or CTRL-H.

-E[c] Identical to the -e optino except that it only operates on terminals that can backspace.

-k[c] Sets the KILL character to c, defaulting to CTRL-U.

- Prints the terminal type on the standard output.

-s Outputs the “setenv” commands [for csh(1)], or “export” and assignment commands [for sh(1)]. The type of commands are determined by the user’s login shell.

-S Only outputs the strings to be placed in the environment variables.

-r Prints the terminal type on the diagnostic output.

-Q Suppresses the printing of the “Erase set to” and “Kill set to” messages.

-I Suppresses printing of the terminal initialization strings.

tset is most useful when included in the .login [for csh] or .profile [for sh] file executed automatically at login, with -m option is given, the first correct mapping prevails.

EXAMPLES

tset gt42
tset - mdialup>300:adm3a-mdialup:dw2-Qr-e#
tset -mdial:ti733-mplug:?hp2621-munknown:?-e-k^U

To use the information created by the -s option for the Bourne shell, (sh), repeat these commands:

tset -s...>/tmp/tset$$
/tmp/tset$$
rm/tmp/tset$$

To use the information for csh, use:

set noglob
set term=(‘tset-S...’)
setenv TERM$term[1]
setenv TERMCAP"$term[2]"
unset term
unset noglob
