UUGETTY(1M) (Basic Networking Utilities) UUGETTY(1M)
NAME
uugetty - set terminal type, modes, speed, and line
discipline
SYNOPSIS
/usr/lib/uucp/getty [ -h ] [ -t timeout ] [ -r ] line
[ speed [ type [ linedisc ] ] ]
/usr/lib/uucp/getty -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 will
allow 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 <carriage-return> characters
may be required before the login message is output. The
human users will be able to handle this slight
inconvenience. 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.
An entry for an intelligent modem or direct line that has a
uugetty on each end must use the -r option. (This causes
uugetty to wait to read a character before it puts out the
login message, thus preventing two uugettys from looping.)
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:

modem such as penril or ventel.
