+.TH TTYS 5
+.SH NAME
+ttys \- terminal initialization data
+.SH DESCRIPTION
+The
+.I ttys
+file is read by the
+.I 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.
+.PP
+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
+.IR getty (8),
+which performs such tasks as baud-rate recognition,
+reading the login name,
+and calling
+.I login.
+For normal lines,
+the character is `0';
+other characters can be used, for example, with hard-wired terminals
+where speed recognition is unnecessary
+or which have special characteristics.
+.RI ( Getty
+will have to be fixed in such cases.)
+The remainder of the line is the terminal's entry
+in the device directory, /dev.
