TSET(1) INTERACTIVE UNIX System TSET(1)
NAME
tset - provide information to set 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 environment variable. tset
initializes or resets the terminal with tput(1). 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 the terminfo database. If the type is not speci-
fied with the -s option, tset creates information for a ter-
minal 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 defined, tset uses the terminfo database
entry. 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 ter-
minal based on this type. If the serial port is not found
in /etc/ttytype, the terminal type is set to unknown.
tset displays the created information at the standard out-
put. 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 follow-
ing examples illustrate how to use this information to
change the variables.
There are the following options:
-e[c]
Sets the ERASE character to c on all terminals. The
default setting is the BACKSPACE, or CTRL-H.
-E[c]
Identical to the -e command 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.
-h Forces tset to search /etc/ttytype for information and
to overlook the environment variable, TERM.

-S Only outputs the strings to be placed in the environ-
ment variables, without the shell commands printed for
-S.
-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, e.g., spawns tput reset instead of tput init.
-m[ident][test baudrate]:type
Allows a user to specify how a given serial port is is
to be mapped to an actual terminal type. The option
applies to any serial port in /etc/ttytype whose type
is indeterminate (e.g., dialup, plugboard, etc.). The
type specifies the terminal type to be used, and ident
identifies the name of the indeterminate type to be
matched. If no ident is given, all indeterminate types
are matched. The test baudrate defines a test to be
performed on the serial port before the type is
assigned. The baudrate must be as defined in stty(1).
The test may be any combination of: >, =, <, @, and !.
If the type begins with a question mark, the user is
asked if he really wants that type. A null response
means to use that type; otherwise, another type can be
entered which will be used instead. The question mark
must be escaped to prevent filename expansion by the
shell. If more than one -m option is given, the first
correct mapping prevails.
tset is most useful when included in the .login [for csh(1)]
or .profile [for sh(1)] file executed automatically at
login, with -m mapping used to specify the terminal type you
most frequently dial in on.
EXAMPLES
tset gt42
tset -mdialup\>300:adm3a -mdialup:dw2 -Qr -e#
tset -m dial:ti733 -m plug:\?hp2621 -m unknown:\? -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 created for csh, use:
