ct(1)

NAME

ct - spawn getty to a remote terminal (call terminal)

SYNOPSIS

ct [-wn] [-xn] [-h] [-v] [-sspeed] telno...

DESCRIPTION

ct dials telno, the telephone number of a modem that is attached to a terminal, and spawns a getty(1M) process to that terminal.

ct tries each line listed in ®le /etc/uucp/Devices until it ®nds an available line with appropriate attributes or runs out of entries. If no lines are free, ct asks whether it should wait for a line, and if so, how many minutes it should wait before giving up. ct searches again for an available line at one-minute intervals until the speci®ed limit is exceeded. Note that normally, ct disconnects the current tty line, so that the line can answer the incoming call. This is because ct assumes that the current tty line is connected to the terminal to spawn the getty process.

The telno argument speci®es the telephone number, which can be composed of characters 0 through 9, -, =, *, and #. Use equal signs to signify secondary dial tones and minus signs for delays at appropriate places. The maximum length of telno is 31 characters. If more than one telephone number is speci®ed, ct tries each in succession until one answers; this is useful for specifying alternate dialing paths.

When ct disconnects the current line, getty should not be spawned on this line if ct is going to make use of the same line to reconnect. To do this, set the entry for this line in the inittab ®le to uugetty instead of getty (see inittab(4)).

Options

ct recognizes the following options and command-line arguments:

-wn

Instruct ct to wait for a line a maximum of n number of minutes, if lines are busy. If

 

this option is speci®ed, ct does not query the user about whether to wait for a line.

-xn

Produce detailed output from program execution on the standard error output. This

 

option is used for debugging. The debugging level n is a single digit; the most useful

 

value is -x9.

-h

Prevent ct from disconnecting ("hanging up") the current tty line. This option is

 

necessary if the user is using a different tty line than the one used by ct to spawn the

 

getty.

-v

Verbose mode. The -voption is used with the -hoption and causes ct to send a

 

running narrative to the standard error output stream.

-sspeed

Set the data rate where speed is expressed in baud. The default rate is 1200.

After the user on the destination terminal logs out, ct prompts, Reconnect? If the response begins with the letter n the line is dropped. Otherwise, getty is restarted and the login: prompt is printed.

Of course, the destination terminal must be attached to a modem that can automatically answer incoming calls.
