spawn login to a remote terminal
ct [options] telno
The ct command dials the telephone number
of a modem that is attached to a terminal and
process to that terminal.
The ct command takes the following options:
By default, ct hangs up the current line so
it can be used to answer the incoming call.
This option prevents this action.
It also waits for the termination of the specified ct process
before returning control to the user's terminal.
This option sets the data rate, where
speed is expressed in baud rates.
The default baud rate is 1200.
This option specifies verbose mode:
ct sends a running narrative
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 this
maxmins is the maximum number of minutes
that ct is to wait for a line.
This option is used for debugging;
it produces a detailed output of the
program execution on standard error.
num is an integer between 0 and 9 inclusive,
where 9 indicates the most detailed debugging information.
The telno argument is a telephone number
with equal signs (=) for secondary dial tones, and minus
signs (-) for delays at appropriate places.
The set of valid characters for telno is:
the digits 0 through 9, ``-'', ``='', ``''
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 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.
If there is no port monitor,
ct prompts with
If the response begins with the letter ``n'',
the line is dropped; otherwise,

The user should log out properly before disconnecting.
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
