LPTCONTROL(8)		    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, ex-
       tended, 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.

FILES

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.
