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.)

FILES
     /etc/ttys
