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’, ’1’, ’2’ or ’3’; zero causes the line to be ignored, one causes it to be effective as a dialup line, two specifies local terminal operation, and three specifies local terminal operation, but does not run logins on that line. 

The second character is used as an argument to getty(8), which performs such tasks as baud-rate recognition, reading the login name, and calling login.  Refer to getty(8) for a list of these special characters and their meanings.

The remainder of the line is the terminal’s entry in the device directory, /dev.
