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
-operator may be any combination of ``>'', ``<'', ``@'', and ``!''; ``>''
-means greater than, ``<'' means less than, ``@'' means equal to

The baud rate is specified as a number and is compared with the speed
of the standard error output (which should be the control terminal).
The terminal type is a string.
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 \fB\-m\fR option argument be placed within single quote characters,
-and that \fBcsh\fR users insert a backslash character (``\e'') before

.SH HISTORY
The \fB@TSET@\fR command appeared in BSD 3.0. The \fBncurses\fR implementation
was lightly adapted from the 4.4BSD sources for a terminfo environment by Eric
\fB@TSET@\fR's most important use). This implementation behaves like 4.4BSD
tset, with a few exceptions specified here.
.PP
-The \fB\-S\fR option of BSD tset no longer works; it prints an error message to stderr
-and dies. The \fB\-s\fR option only sets \fBTERM\fR, not \fBTERMCAP\fP. Both these
-changes are because the \fBTERMCAP\fR variable is no longer supported under
-terminfo-based \fBncurses\fR, which makes \fB@TSET@ \-S\fR useless (we made it die
-noisily rather than silently induce lossage).

not documented or useful, but were retained as they appear to be in
widespread use. It is strongly recommended that any usage of these

-omitted from the usage summary above.
