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.
