    TTYS(V)                      2/11/75                      TTYS(V)

    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.)
