     getty -- set terminal mode

     getty [type [tty]]

     The getty utility is called by init(8) to open and	initialize the tty
     line, read	a login	name, and invoke login(1).

     The argument tty is the special device file in /dev to open for the ter-
     minal (for	example, ``ttyh0'').  If there is no argument or the argument
     is	`-', the tty line is assumed to	be open	as file	descriptor 0.

     The type argument can be used to make getty treat the terminal line spe-
     cially.  This argument is used as an index	into the gettytab(5) database,
     to	determine the characteristics of the line.  If there is	no argument,
     or	there is no such table,	the default table is used.  If there is	no
     /etc/gettytab a set of system defaults is used.  If indicated by the ta-
     ble located, getty	will clear the terminal	screen,	print a	banner head-
     ing, and prompt for a login name.	Usually	either the banner or the login
     prompt will include the system hostname.

     Most of the default actions of getty can be circumvented, or modified, by
     a suitable	gettytab table.

     The getty utility can be set to timeout after some	interval, which	will
     cause dial	up lines to hang up if the login name is not entered reason-
     ably quickly.


     ttyxx: No such device or address.
     ttyxx: No such file or address.

     A terminal	which is turned	on in the 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 configura-
     tion, or the special file in /dev does not	exist.

     login(1), ioctl(2), tty(4), gettytab(5), ttys(5), init(8)

     A getty utility appeared in Version 6 AT&T	UNIX.
