+.Sh NAME
+.Nm getty
+.Nd set terminal mode
+.Sh SYNOPSIS
+.Nm getty
+.Oo 
+.Ar type
+.Op Ar tty
+.Oc
+.Sh DESCRIPTION
+The
+.Nm getty
+program
+is called by
+.Xr init 8
+to open and initialize the tty line, read a login name, and invoke
+.Xr login 1 .
+.Pp
+The argument
+.Ar tty
+is the special device file in
+.Pa /dev
+to open for the terminal (for example, ``ttyh0'').
+If there is no argument or the argument is
+.Ql Fl ,
+the tty line is assumed to be open as file descriptor 0.
+.Pp
+The
+.Ar type
+argument can be used to make
+.Nm getty
+treat the terminal line specially.
+This argument is used as an index into the
+.Nm gettytab 5
+database, to determine the characteristics of the line.
+If there is no argument, or there is no such table, the
+.Em default
+table is used.
+If there is no
+.Pa /etc/gettytab
+a set of system defaults is used.
+If indicated by the table located,
+.Nm getty
+will clear the terminal screen,
+print a banner heading,
+and prompt for a login name.
+Usually either the banner or the login prompt will include
+the system hostname.
+.Pp
+Most of the default actions of
+.Nm getty
+can be circumvented, or modified, by a suitable
+.Nm gettytab
+table.
+.Pp
+The
+.Nm getty
+program
+can be set to timeout after some interval,
+which will cause dial up lines to hang up
+if the login name is not entered reasonably quickly.
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "ttyxx: No such device or address."
+.It "ttyxx: No such file or address."
+A terminal which is turned
+on in the
+.Xr ttys
+file cannot be opened, likely because the requisite
+lines are either not configured into the system, the associated device
+was not attached during boot-time system configuration,
+or the special file in
+.Pa /dev
+does not exist.
