uugetty - Sets the terminal type, modes, speed, and line.
/usr/lib/uucp/uugetty [-h] [-t time] [-r] [-c file] line
[speed_label [terminal [line_discipline]]]
Directs that the specified file should be checked instead
of the /etc/uugettydefs file. Holds the carrier during
the initialization phase; does not hang up. Specifies a
timeout period for login; in other words, the line is
dropped if nothing is typed after time seconds. Specifies
that uugetty should wait for a character before it displays
a login message, thus preventing two uugetty commands
from looping and allowing the line to be shared by
uucico, cu, and tip.
The uugetty command sets and manages terminals by setting
up speed, terminal flags, and the line discipline. If
command options are provided, uugetty adapts the system to
those specifications; uugetty prints the login prompt,
waits for the user to enter a username, and invokes the
login command.
The uugetty command provides all the features of the getty
command, but also provides support through the -r option
for using the line with the uucico, cu, ct, and tip commands.
The line can thereby be used in both directions.
The uugetty command enables users to log in, but if the
line is free, the uucico, cu, ct, and tip commands can be
used for dialing out. The implementation depends on the
fact that the uucico, cu, ct, and tip commands create lock
files when devices are used. When uugetty first reads
characters, the status of the lock file indicates whether
the line is being used by uucico, cu, ct, or tip, or by
someone trying to log in.
The line argument specifies the /dev/entry file for the
terminal line. It can be entered as a relative pathname
or an absolute pathname. The speed_label argument is a
pointer into the /etc/uugettydefs file where the definitions
for speed and other associated flags are located. If
this argument is not specified, uugetty uses the first
entry in the file. The terminal argument specifies the
name of the terminal type. This argument is used to set
the TERM environment variable for the user who logs in
from this terminal. The line_discipline argument specifies
the name of the line discipline.
When the -r option is used, the user may have to key several
carriage returns before the login message is displayed.
When uucico attempts to log in, the following
login script informs it that several carriage returns may
be necessary before the login message is displayed:
\r\d\r\d\r\d\r in:--in:login sequence
In this script, login sequence is whatever is normally
used for the login sequence.
An entry for an intelligent modem or direct line that has
a uugetty on each end must use the -r option. The following
is an /etc/inittab entry using uugetty on an intelligent
modem or direct line:
30:2:respawn:/usr/lib/uucp/uugetty -r -t 60 tty12 1200
