\&\fBTset\fR initializes terminals.
\fBTset\fR first determines the type of terminal that you are using.

+If the terminal type was not specified on the command-line, the \fB\-m\fR
option mappings are then applied (see below for more information).
Then, if the terminal type begins with a question mark (``?''), the
user is prompted for confirmation of the terminal type. An empty

The options are as follows:

The terminal type is displayed to the standard output, and the terminal is
not initialized in any way. The option `-' by itself is equivalent but
archaic.

Do not send the terminal or tab initialization strings to the terminal.

Don't display any values for the erase, interrupt and line kill characters.

-\fB-V\fR

Set the line kill character to \fIch\fR.

Specify a mapping from a port type to a terminal.
See below for more information.

Print the terminal type to the standard error output.

Print the sequence of shell commands to initialize the environment variable
\fBTERM\fR to the standard output.
See the section below on setting the environment for details.

options may either be entered as actual characters or by using the `hat'
notation, i.e. control-h may be specified as ``^H'' or ``^h''.
.SH SETTING THE ENVIRONMENT
It is often desirable to enter the terminal type and information about
the terminal's capabilities into the shell's environment.
-This is done using the -s option.

the \fBSHELL\fR environmental variable ends in ``csh'', the commands
are for \fBcsh\fR, otherwise, they are for \fBsh\fR.

or \fB.profile\fR files will initialize the environment correctly:

provide information about the type of terminal used on such ports.

from some set of conditions to a terminal type, that is, to
tell \fBtset\fR
``If I'm on this port at a particular speed, guess that I'm on that
kind of terminal''.

-The argument to the -m option consists of an optional port type, an
+The argument to the \fB\-m\fR option consists of an optional port type, an
optional operator, an optional baud rate specification, an optional
colon (``:'') character and a terminal type. The port type is a
string (delimited by either the operator or the colon character). The

The terminal type is a string.

+If the terminal type is not specified on the command line, the \fB\-m\fR
mappings are applied to the terminal type. If the port type and baud
rate match the mapping, the terminal type specified in the mapping
replaces the current type. If more than one mapping is specified, the
.PP
If no baud rate is specified, the terminal type will match any baud rate.
If no port type is specified, the terminal type will match any port type.
-For example, \fB-m dialup:vt100 -m :?xterm\fR
+For example, \fB\-m dialup:vt100 \-m :?xterm\fR
will cause any dialup port, regardless of baud rate, to match the terminal
type vt100, and any non-dialup port type to match the terminal type ?xterm.
Note, because of the leading question mark, the user will be
queried on a default port as to whether they are actually using an xterm
terminal.

-No whitespace characters are permitted in the -m option argument.
+No whitespace characters are permitted in the \fB\-m\fR option argument.
Also, to avoid problems with meta-characters, it is suggested that the
-entire -m option argument be placed within single quote characters,

and that \fBcsh\fR users insert a backslash character (``\e'') before
any exclamation marks (``!'').

.PP
There was an undocumented 4.4BSD feature that invoking tset via a link named
`TSET` (or via any other name beginning with an upper-case letter) set the
terminal to use upper-case only. This feature has been omitted.
