uugetty(1M) UNIX System V(Basic Networking Utilities) uugetty(1M)
NAME
uugetty - set terminal type, modes, speed, and line discipline
SYNOPSIS
/usr/lib/uucp/uugetty [-t timeout] [-r] line [speed [type [linedisc] ] ]
/usr/lib/uucp/uugetty -c file
DESCRIPTION
uugetty is identical to getty(1M) but changes have been made to support
using the line for uucico, cu, and ct; that is, the line can be used in
both directions. The uugetty allows users to login, but if the line is
free, uucico, cu, or ct can use it for dialing out. The implementation
depends on the fact that uucico, cu, and ct create lock files when
devices are used. When the open returns (or the first character is read
when -r option is used), the status of the lock file indicates whether
the line is being used by uucico, cu, ct, or someone trying to login.
Note that in the -r case, several RETURN characters may be required
before the login message is output. uucico trying to login will have to
be told by using the following login script:
"" \r\d\r\d\r\d\r in:--in: . . .
where the ``. . .'' is whatever would normally be used for the login
sequence.
If there is a uugetty on one end of a direct line, there must be a
uugetty on the other end as well. Here 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
The meanings of the available options are
-t timeout
Specifies that uugetty should exit if the open on the line succeeds
and there is no response to the login prompt in timeout seconds.
timeout is replaced by an integer.
-r Causes uugetty to wait to read a character before it puts out the
login message, thus preventing two uugettys from looping. An entry
for an intelligent modem or direct line that has a uugetty on each
end must use this option.
line Defines the name of the line to which uugetty will attach itself.
The line name will point to an entry in the /dev directory. For
example, /dev/tty03.
speed Defines the entry to use from the /usr/lib/saf/ttymondefs file.
The entry defines the line speed, the login message, the initial
tty setting, and the next speed to try if the user says the speed
is inappropriate (by sending a break character). The default speed
is 300.
type Defines the type of terminal connected to the line. The default
terminal is none, representing a normal terminal unknown to the
system.

linedisc
Sets the line discipline to use on the line. The default is
LDISC0, which is the only one currently compiled into the operating
system.

-c file
Checks the speed and tty definitions in file and sends the results
to standard output. Unrecognized modes and improperly constructed
entries are reported. For correct entries, flag values are
printed. file is replaced by /usr/lib/saf/ttymondefs or a
similarly structured file.

NOTES
ct does not work when uugetty is used with an intelligent modem such as
Penril or Ventel.
