lptcontrol - a utility for manipulating the lpt printer driver
lptcontrol -e -| -i -| -p -| -s [-d control_device]
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.
