6 ttys - terminal initialization data

9 The ttys file is read by the init program and specifies which terminal
10 special files are to have a process created for them which will allow
11 people to log in. It contains one line per special file.
12
13 The first character of a line is either `0' or `1'; the former causes
14 the line to be ignored, the latter causes it to be effective. The sec‐
15 ond character is used as an argument to getty(8), which performs such
16 tasks as baud-rate recognition, reading the login name, and calling
17 login. For normal lines, the character is `0'; other characters can be
18 used, for example, with hard-wired terminals where speed recognition is
19 unnecessary or which have special characteristics. (Getty will have to
20 be fixed in such cases.) The remainder of the line is the terminal's
21 entry in the device directory, /dev.
