ct - spawn login to a remote terminal
ct [ options ] telno...
SUNWbnuu
ct dials the telephone number of a modem
that is attached to a terminal and spawns a login process to that terminal.
The 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 telno is 31
characters). If more than one telephone number is specified, ct will try
each in succession until one answers; this is useful for specifying alternate
dialing paths.
ct will try each line listed in the file /etc/uucp/Devices
until it finds an available line with appropriate attributes, or runs out
of entries.
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 will be dropped; otherwise,
ttymon will be started again and the login: prompt will be 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.
- -h
- Normally, ct will hang up the current line so that it can be
used to answer the incoming call. The -h option will prevent this action.
The -h option will also wait for the termination of the specified ct process
before returning control to the user’s terminal.
- -sspeed
- 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 will send a
running narrative to the standard error output stream.
- -wn
- If there are no
free lines ct will ask if it should wait for one, and if so, for how many
minutes it should wait before it gives up. ct 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 -wn option. 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
stderr. n is a single number between 0 and 9. As n increases to 9, more detailed
debugging information is given.

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)
).
