NAME
       ttys - terminal initialization data

DESCRIPTION
       The  ttys  file	is  read  by the init program and specifies which terminal special files are to have a process created for them which will
       allow people to log in.	It contains one line per special file.

       The first character of a line is either `0' or `1'; the former causes the line to be ignored, the latter causes it to  be  effective.   The
       second  character is used as an argument to getty(8), which performs such tasks as baud-rate recognition, reading the login name, and call-
       ing login.  For normal lines, the character is `0'; other characters can be used, for example, with hard-wired terminals where speed recog-
       nition  is  unnecessary	or which have special characteristics.	(Getty will have to be fixed in such cases.)  The remainder of the line is
       the terminal's entry in the device directory, /dev.
