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.
