GETTY(8)		  BSD System Manager's Manual		      GETTY(8)

NAME
     getty -- set terminal mode

SYNOPSIS
     getty [type [tty]]

DESCRIPTION
     The getty program 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(5) table.

     The 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 reason-
     ably quickly.

RESOURCES
     getty is started by init(8), with a process priority, umask, and resource
     limits based on the "default" entry in /etc/login.conf.

FILES
     /etc/gettytab

DIAGNOSTICS
     ttyxx: No such device or address.
     ttyxx: No such file or address.  A	terminal which is turned on in the
     ttys(5) file cannot be opened, likely because the requisite lines are ei-
     ther not configured into the system, the associated device	was not	at-
     tached during boot-time system configuration, or the special file in /dev
     does not exist.
