mgettydefs(4)

mgettydefs – speed and terminal settings used by mgetty

Description

The /etc/gettydefs file contains information used by mgetty(1) to set up the speed and terminal settings for a line. It also supplies information on what the login prompt should look like. Many versions of UNIX have a version of getty(1) that also reads /etc/gettydefs. Both mgetty and getty expect similar formats in /etc/gettydefs except that, when used by mgetty, extended functionality is available. Even so, the additional functions are simply ignored by standard getty, so they can co-exist using the same file. Note, however, that mgetty can be compiled to use a file different from /etc/gettydefs if your getty gets upset about the extensions. This manual page documents /etc/gettydefs and describes the extended functionality available when used by mgetty(1). This document will refer to getty(1) except where mgetty‘s behaviour is different. Each entry in /etc/gettydefs has the following format:

label# initial-flags # final-flags # login-prompt #next-label

Each entry is followed by a blank line. The login prompt field can contain quoted characters which will be converted to other values. The sequences and their substitutions are:

newline

carriage return

\g

beep



backspace



vertical tab (VT)

formfeed

tab

\L

portname

\C

time in ctime(3) format.

\N
