ct(1C) USER COMMANDS ct(1C)
NAME
ct - spawn login to a remote terminal
SYNOPSIS
ct [options] telno ...
DESCRIPTION
ct dials the telephone number of a modem that is attached to
a terminal and spawns a login process to that terminal.
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 attri-
butes, or runs out of entries. ct uses the following
options:
-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.

ct(1C) USER COMMANDS ct(1C)
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 moni-
toring the port, the port monitor reissues the login:
prompt.
The user should log out properly before disconnecting.

NOTES
The ct program will not work with a DATAKIT Multiplex inter-
face.
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)).
