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.
