.Sh DESCRIPTION
|
||
|
|
This driver provides access to parallel ports. It assumes that
|
||
|
|
the parallel port controller will not cause an interrupt, and
|
||
|
|
therefore must poll the controller.

.Sh BUGS
|
||
|
|
This driver only exists to support broken parallel port implementations.
|
||
|
|
Systems with properly working parallel ports should use the
|
||
|
|
.Nm lpt
|
||
|
|
driver instead, as it is less resource-hungry.
|
||
|
|
.Pp
|
||
|
|
This driver could stand a rewrite.
