- .th TTYS V 2/11/75
- .sh NAME
- ttys \*- typewriter initialization data
- .sh DESCRIPTION
- The
- .it ttys
- file is read by the
- .it 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.
- .s3
- The first character is either `0' or `1';
- the former causes the line to be ignored,
- the latter causes it to be effective.
- The second character is the last character in the name
- of a typewriter; e.g. \fIx\fR refers to
- the file `/dev/tty\fIx\fR'.
- The third character is used as an argument
- to the
- .it getty
- program,
- which performs such tasks as baud-rate recognition,
- reading the login name,
- and calling
- .it login.
- For normal lines,
- the character is `0';
- other characters can be used, for example, with hard-wired terminals
- where speed recognition is unnecessary
- or which have special characteristics.
- (Getty will have to be fixed in such cases.)
- .sh FILES
- /etc/ttys
- .sh "SEE ALSO"
- init (VIII), getty (VIII), login (I)
