qterm - Query Terminal
qterm [ +|-alt ] [ +|-always ] [ +|-longname ] [ +|-quiet ] [ +|-sent ] [ +|-timeout ] [
+|-usrtab ] [ +|-watch ] [ +|-systab ] [ -wait interval ] [ -file tabfile ]
Qterm is used to query a terminal to determine its name. This is done by sending a spe-
cial sequence to the terminal, reading in a response, and comparing it against a table of
possible responses. The ``name'' printed to standard output should be one found in the
termcap(5) (or terminfo(5) for System V systems) database.
For csh(1) users, putting a line in your .login file such as:
setenv TERM `qterm`
should automagically set your terminal type. For sh(1) users, putting these lines in your
.profile file should set your terminal type:
By default, qterm uses the system tab file /usr/local/lib/qtermtab to obtain information
for querying terminals.
+alt Use the alternate string ``<ESCAPE>[c'' when asking the terminal to identify
itself. This string is recognized by most ANSI compatible terminals.
-alt Don't use the alternate string, but the string found in the tabfile being used.
This is the default.
Always send the terminal query string. Normally the query string is only sent if
it differs from the last string sent.
Only send the terminal query string if it differs from the last string sent. This
is the default.
Use <tabfile> to find information for querying the terminal.
Print only the long (verbose) terminal name.
Don't print the long (verbose) terminal name. This is the default.
+quiet Be quiet and only print the terminal name to standard output.
-quiet Don't be quiet and only print the terminal name to standard output. This is the
+watch Watch the characters sent and recieved to the terminal.
-watch Don't watch the characters sent and recieved to the terminal. This is the default.
Wait for timeout when listening for response string. This is useful if the first
entry in a qtermtab doesn't have a response string with an ending character that is
common with the rest of the qtermtab entries.
Disable waiting for timeout when listening for response string. This is the
Use $HOME/.qtermtab to find information for querying the terminal.
Don't use $HOME/.qtermtab to find information for querying the terminal. This is
+sent Display the final response sent from the terminal in a ``nice'' fashion.
-sent Don't display the final response sent from the terminal. This is the default.
Use /usr/local/lib/qtermtab to find information for querying the terminal. This is
Don't use system tab file to find information for querying the terminal.
Set the wait (timeout) period to interval (in seconds).
The format of the file $HOME/.qtermtab and qterm's system tab file
/usr/local/lib/qtermtab, consists of four fields each seperated by white space (tabs
and/or spaces). The first field is the string that should be used to query the terminal.
The second field is the string to expect in response to the query. The third field is the
terminal name (compatible with termcap(5)) to print to standard output. The fourth field
is optional and may contain a description of the exact manufacturer and model name of the
terminal to be used in a message printed to standard error.
Blank lines or lines starting with the character ``#'' are ignored and may be used as com-
ment lines. A character preceeded by a ``^'' is taken to mean the control character.
(i.e. ``^['' is interpretted as an <ESCAPE>). Both the send and receive (first and sec-
ond) fields may contain octal values preceeded by a `\'. (i.e. <ESCAPE> can be repre-
sented by `\033'.)
The ``expect'' (second) field can be a regular expression denoted by a leading backslash
(`\'). i.e. "^[[123" matches the string "^[[123", whereas "^[\" matches "^[1" or
"^[2" or "^[3". See ed(1) for regular expression information.

Terminal not recognized - defaults to dumb.
QTerm did not receive a response from the terminal, or the response did not match
any that qterm has stored internally. Use the +watch option to check to see which
is the case.
Many terminals do not send a response at all.
