Parallel port is polled? I wish.
As far as I could gather from the sources, PLIP accesses the parallel port
only upon interrupt, which should make it as CPU intensive as a network card
(ignoring the various technical details, that is).
If you know how to make PLIP poll the parallel port and not require
an IRQ line, please let me know, as it can greatly help me in the future.
I'm willing to pay in speed to get this thing working in several machines
where I don't have too much of a choice regarding the IRQ of the parallel
port.
Actually, I even started looking into the sources wishing to implement
something like that, but gave up shortly after when my immediate problem was
solved otherwise.
