GETTY(8) System Manager's Manual GETTY(8) NAME getty - set terminal mode SYNOPSIS /etc/getty [ char ] DESCRIPTION Getty is invoked by init(8) after a terminal is opened. While reading the user's name getty attempts to adapt the system to the speed and type of terminal being used. Init calls getty with an argument specified by the ttys(5) entry for the terminal line. The argument char determines the line speed and other characteristics; see below. Getty then types a banner identify- ing the system (from and the message. The user's name is then read, a character at a time. If a null character is received, it is assumed to be the result of the user pushing the `break' (`interrupt') key. The speed is then changed to another baud rate and is typed again. Succes- sive breaks cycle through a set of speeds. The user's name is terminated by a newline or carriage return. The latter results in the system being set to treat carriage returns appro- priately (see ioctl(2)). Finally, login(8) is called with the user's name as argument. Here are the possible values for char. If more than one speed is given, the first speed is used initially; others are selected by suc- cessive depressions of the BREAK key. Other things, like delays and tab expansion, are set in various ways as well. char speed 0 300-1200-150-110 2 9600 3 1200-300 4 300 5 300-1200 6 2400 7 4800 8 9600-1200-300 9 300-9600-1200 a 2400-1200 b 1200-2400 j exta (usually 19200) SEE ALSO init(8), login(8), ioctl(2), ttys(5) GETTY(8)
