NAME
ttys - typewriter initialization data
DESCRIPTION
The ttys file is read by the init program and specifies
which typewriter special files are to have a process created
for them which will allow people to log in. It consists of
lines of 3 characters each.
The first character is either `0' or `1'; the former causes
the line to be ignored, the latter causes it to be effec-
tive. The second character is the last character in the
name of a typewriter; e.g. x refers to the file `/dev/ttyx'.
The third character is used as an argument to the getty pro-
gram, which performs such tasks as baud-rate recognition,
reading the login name, and calling login. For normal
lines, the character is `0'; other characters can be used,
for example, with hard-wired terminals where speed recogni-
tion is unnecessary or which have special characteristics.
(Getty will have to be fixed in such cases.)
