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

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.
