LPTCONTROL(8)		FreeBSD	System Manager's Manual		 LPTCONTROL(8)

NAME
     lptcontrol	-- a utility for manipulating the lpt printer driver

SYNOPSIS
     lptcontrol	-e | -i	| -p | -s [-d control_device]

DESCRIPTION
     The lptcontrol utility is used to set either the interrupt-driven,
     extended, standard, or polling mode of individual lpt(4) devices.	When a
     printer is	switched from a	mode to	another, this change will only take
     effect the	next time the device is	opened.

     Extended mode is anything the parallel port interface can support.	 For
     an	ECP/ISA	parallel port, it may be FIFO+DMA or ECP.

     The following command line	options	are supported:

     -e	     Turn on extended mode.

     -i	     Turn on interrupt-driven mode.

     -p	     Turn on polled mode.

     -s	     Turn on standard mode, i.e., turn off extended mode.

     -d	control_device
	     Set the mode of the printer control device	specified by
	     control_device.  The default value	for control_device is
	     /dev/lpt0.ctl.

     One of -e,	-i, -p or -s must be specified.

HISTORY
     The lptcontrol utility first appeared in FreeBSD 1.1.5

AUTHORS
     Geoffrey M. Rehmet

BUGS
     The control device	name should never have been an option, but should have
     been an optional argument.	 Because of this, a single argument is treated
     as	a device name.
