Q T E R M - Q U E R Y T E R M I N A L
Revision 1.11
Qterm is a program that queries terminals to find out what kind
of terminal is responding. It is useful to automagically define your
terminal type. It prints the name of the terminal (compatible, hopefully,
with a termcap/terminfo name) such as "vt100" to standard output.
See the manual for details.
Qterm was written under 4.2BSD and will probably run without
modification on other Berkeley Unix systems. It will require some
minor tweaking to work under USG (System III & V.?, V?). Most of this
should be only in setting/unsetting cbreak and echo modes. If you
do port it to Sys V, please send me a copy and I'll incorporate it into
my version.
If you add any new terminal's to the master table, please send
me the output of a "qterm -s" and I'll add it to my table.

.SH NAME
qterm \- Query Terminal
.SH SYNOPSIS
qterm
[
.B \-a
]
[
.B \-s
]
[
.B \-q
]
.SH DESCRIPTION
.I Qterm
is used to query a terminal to determine its name.
This is done by sending the fairly universal
string ``<ESCAPE>Z'' to the terminal,
reading in a response, and comparing it against a master table of possible
responses.
The ``name'' printed to standard output should be one found in
the
.I termcap(5)
database.
.PP
Putting a line in your .login file such as:
.sp 1
.in +.5i
setenv TERM `qterm`
.in -.5i
.sp 1
should automagically set your terminal type.
.SH OPTIONS
.IP \-a
Use the alternate string ``<ESCAPE>[c'' when asking the terminal to
identify itself. This string is recognized by most ANSI compatible
terminals.
.IP \-s
Display the response received from
the terminal in a ``nice'' fashion.
.IP \-q
Be ``quiet'' and only print the terminal name to standard
output.
.SH AUTHOR
Michael A. Cooper,

.SH FILES
/etc/termcap \- termcap(5) database
.SH SEE ALSO
termcap(5)
.SH DIAGNOSTICS
The message, ``Terminal not recognized - defaults to dumb.'', means
that
.I qterm
did not receive a response from the terminal, or the response
did not match any that
.I qterm
has stored internally. Use the \-s option to check to see which
is the case.
.SH BUGS
Many terminals do not send a response at all.
