Parallel port network interface
|
|
.Sh SYNOPSIS
|
|
.Cd "device plip at ppbus?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Em plip
|
|
driver is the port of the
|
|
.Xr lp 4
|
|
driver to the
|
|
.Xr ppbus 4
|
|
system.
|
|
.Pp
|
|
One purpose of this port is to allow parallel port sharing with other
|
|
parallel devices. Parallel port bus allocation has been added to the original
|
|
.Xr lp 4
|
|
driver. Secondly, inb()/outb() calls have been replaced by ppbus function
|
|
calls. plip is now arch-independent thanks to the ppbus interface. See
|
|
.Xr ppbus 4
|
|
for more info about the ppbus system.
|
|
.Pp
|
|
The ppbus is allocated when the parallel network interface comes up, then
|
|
released when the interface goes down. Consequently, the parallel port bus
|
|
is unavailable to other devices when the network interface is up. plip is
|
|
interrupt driven and needs to own the bus to receive parallel port interrupts.
|
|
.Pp
|
|
Please, ensure the
|
|
.Xr ppc 4
|
|
entry in you MACHINE file has the net interrupt level...
