NAME
ct - spawn login to a remote terminal
SYNOPSIS
ct [options] telno . . .
DESCRIPTION
The ct command dials the telephone number of a modem that is
attached to a terminal and spawns a login process to that
terminal.
Files
/etc/uucp/Devices
USAGE
telno 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 telno is 0 through 9, -, =,
**, and #. The maximum length of telno is 31 characters). If
more than one telephone number is specified, ct tries each in
succession until one answers; this is useful for specifying
alternate dialing paths.
ct tries each line listed in the file /etc/uucp/Devices until
it finds an available line with appropriate attributes, or
runs out of entries.
ct takes the following options:
-h Normally, ct hangs up the current line so it can
be used to answer the incoming call. The -h
option prevents this action. The -h option also
waits for the termination of the specified ct
process before returning control to the user's
terminal.
-s speed The data rate may be set with the -s option.
speed is expressed in baud rates. The default
baud rate is 1200.
-v If the -v (verbose) option is used, ct sends a
running narrative to the standard error output
stream.

-w n If there are no free lines ct asks if it should
wait for one, and if so, for how many minutes it
should wait before it gives up. ct continues to
try to open the dialers at one-minute intervals
until the specified limit is exceeded. This
dialogue may be overridden by specifying the -w n
option where n is the maximum number of minutes
that ct is to wait for a line.
-xn This option is used for debugging; it produces a
detailed output of the program execution on
standard error. n is a single number between 0
and 9. As n increases to 9, more detailed
debugging information is given.
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, ct prompts: Reconnect? If the response begins with
the letter n, the line is dropped; otherwise, ttymon is
started again and the login: prompt is printed. In the second
case, where a port monitor is monitoring the port, the port
monitor reissues the login: prompt.
The user should log out properly before disconnecting.
Warnings
The ct program will not work with a DATAKIT Multiplex
interface.
For a shared port, one used for both dial-in and dial-out, the
ttymon program running on the line must have the -r and -b
options specified [see ttymon(1M)].
