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


NAME

     lptcontrol -- a utility for manipulating the lpt printer driver


SYNOPSIS

     lptcontrol -i | -p | -e | -s [-d device]


DESCRIPTION

     The lptcontrol utility is used to set either the interrupt-driven,
     extended 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:

     -i      Turn on interrupt-driven mode.

     -p      Turn on polled mode.

     -e      Turn on extended mode.

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

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

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