dials telno, the telephone number of a modem that is attached to a ter‐
minal, and spawns a getty(1M) process to that terminal.
tries each line listed in file until it finds an available line with
appropriate attributes or runs out of entries. If no lines are free,
asks whether it should wait for a line, and if so, how many minutes it
should wait before giving up. searches again for an available line at
one-minute intervals until the specified limit is exceeded. Note that
normally, disconnects the current tty line, so that the line can answer
the incoming call. This is because assumes that the current tty line
is connected to the terminal to spawn the process.
The telno argument specifies the telephone number, which can be com‐
posed of characters through and Use equal signs to signify secondary
dial tones and minus signs for delays at appropriate places. The maxi‐
mum length of telno is 31 characters. If more than one telephone num‐
ber is specified, tries each in succession until one answers; this is
useful for specifying alternate dialing paths.
When disconnects the current line, should not be spawned on this line
if is going to make use of the same line to reconnect. To do this, set
the entry for this line in the file to instead of (see inittab(4)).
recognizes the following options and command-line arguments:
Instruct to wait for a line a maximum of n number of min‐
utes, if lines are busy. If this option is spec‐
ified, does not query the user about whether to
wait for a line.
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
Prevent 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
to spawn the
Verbose mode. The option is used with the option and causes to
send a running narrative to the standard error
Set the data rate where
speed is expressed in baud. The default rate is
After the user on the destination terminal logs out, prompts, If the
response begins with the letter the line is dropped. Otherwise, is
restarted and the prompt is printed.
Of course, the destination terminal must be attached to a modem that
can automatically answer incoming calls.
