+.Sh NAME
+.Nm ttys
+.Nd terminal initialization information
+.Sh DESCRIPTION
+The file
+.Nm ttys
+contains information that is used by various routines to initialize
+and control the use of terminal special files.
+This information is read with the
+.Xr getttyent 3
+library routines.
+There is one line in the 
+.Nm ttys
+file per special device file.
+Fields are separated by tabs and/or spaces.
+Fields comprised of more than one word should be enclosed in double
+quotes (``"'').
+Blank lines and comments may appear anywhere in the file; comments
+are delimited by hash marks (``#'') and new lines.
+Any unspecified fields will default to null.
+.Pp
+The first field is the
+name of the terminal special file as it is found in
+.Pa /dev .
+.Pp
+The second field of the file is the command to execute for the line,
+usually
+.Xr getty 8 ,
+which initializes and opens the line, setting the speed, waiting for
+a user name and executing the
+.Xr login 1
+program.
+It can be, however, any desired command, for example
+the start up for a window system terminal emulator or some other
+daemon process, and can contain multiple words if quoted.
+.Pp
+The third field is the type of terminal usually connected to that
+tty line, normally the one found in the
+.Xr termcap 5
+data base file.
+The environment variable
+.Dv TERM
+is initialized with the value by
+either
+.Xr getty 8
+or
+.Xr login 1 .
+.Pp
+The remaining fields set flags in the
+.Fa ty_status
+entry (see
+.Xr getttyent 3 )
+or specify a window system process that
+.Xr init 8
+will maintain for the terminal line.
+.Pp
+As flag values, the strings ``on'' and ``off'' specify that
+.Xr init
+should (should not) execute the command given in the second field,
+while ``secure'' (if ``on'' is also specified) allows users with a
+uid of 0 to login on
+this line.
+The flags ``local'', ``rtscts'', ``mdmbuf'', and ``softcar''
+modify the default behaviour of the terminal line, and their actions
+are driver dependent.
+The ``local'' flag causes the driver to
+treat the line as if it locally connected.
+The ``rtscts'' flag
+instructs the driver to use RTS/CTS hardware flow control, if
+possible.
+The ``mdmbuf'' flag instructs the driver to use
+DTR/DCD flow control, if possible.
+The ``softcar'' flag causes the driver to ignore
+hardware carrier on the line.
+These flag fields should not be quoted.
+.Pp
+The string ``window='' may be followed by a quoted command
+string which
+.Xr init
+will execute
+.Em before
+starting the command specified by the second field.
