.SH NAME
ct \- spawn login to a remote terminal
.SH SYNOPSIS
.LP
.nf
\fBct\fR [\fIoptions\fR] \fItelno\fR...
.fi

.SH DESCRIPTION
.sp
.LP
The \fBct\fR utility dials the telephone number of a modem that is attached to
a terminal and spawns a \fBlogin\fR process to that terminal. The \fItelno\fR
is a telephone number, with equal signs for secondary dial tones and minus
signs for delays at appropriate places. (The set of legal characters for
\fItelno\fR is 0 through 9, -, =, *, and #. The maximum length \fItelno\fR is
31 characters). If more than one telephone number is specified, \fBct\fR will
try each in succession until one answers; this is useful for specifying
alternate dialing paths.
.sp
.LP
\fBct\fR will try each line listed in the file \fB/etc/uucp/Devices\fR until it
finds an available line with appropriate attributes, or runs out of entries.
.sp
.LP
After the user on the destination terminal logs out, there are two things that
could occur depending on what type of port monitor is monitoring the port. In
the case of no port monitor, \fBct\fR prompts: \fBReconnect?\fR If the response
begins with the letter \fBn\fR, the line will be dropped; otherwise,
\fBttymon\fR will be started again and the \fBlogin:\fR prompt will be printed.
In the second case, where a port monitor is monitoring the port, the port
monitor reissues the \fBlogin:\fR prompt.
.sp
.LP
The user should log out properly before disconnecting.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-h\fR\fR
.ad
.RS 11n
Normally,  \fBct\fR will hang up the current line so that it can be used to
answer the incoming call.  The \fB-h\fR option will prevent this action. The
\fB-h\fR option will also wait for the termination of the specified \fBct\fR
process before returning control to the user's terminal.
.RE

.sp
.ne 2
.na
\fB\fB-s\fR\fIspeed\fR\fR
.ad
.RS 11n
The data rate may be set with the \fB-s\fR option. \fIspeed\fR is expressed in
baud rates.  The default baud rate is 1200.
.RE

.sp
.ne 2
.na
\fB\fB-v\fR\fR
.ad
.RS 11n
If the \fB-v\fR (verbose) option is used,  \fBct\fR will send a running
narrative to the standard error output stream.
.RE

.sp
.ne 2
.na
\fB\fB-w\fR\fIn\fR\fR
.ad
.RS 11n
If there are no free lines \fBct\fR will ask if it should wait, and for how
many minutes,  before it gives up. \fBct\fR will continue to try to open the
dialers at one-minute intervals until the specified limit is exceeded. This
dialogue may be overridden by specifying the \fB-w\fR\fIn\fR option. \fIn\fR is
the maximum number of minutes that \fBct\fR is to wait for a line.
.RE

.sp
.ne 2
.na
\fB\fB-x\fR\fIn\fR\fR
.ad
.RS 11n
This option is used for debugging; it produces a detailed output of the program
execution on stderr. \fIn\fR is a single number between 0 and 9. As \fIn\fR
increases to 9, more detailed debugging information is given.

.SH NOTES
.sp
.LP
The \fBct\fR program will not work with a DATAKIT Multiplex interface.
.sp
.LP
For a shared port, one used for both dial-in and dial-out, the \fBttymon\fR
program running on the line must have the \fB-r\fR and \fB-b\fR options
specified (see \fBttymon\fR(8)).
