No, I've since checked, and it really does say "ORINET".

Thanks for the suggestion, but I failed to find anything helpful.

Well, it seems once to have been supported, by "modprobe parport_pc ..."
for the parallel port, and by recompiling the kernel for the serial
ports, but neither works on a recent version of linux: parport_pc does
nothing [1], while the compilation fails because of a mismatch between
the supplied code and current kernel header files.

NetMos/MOSChip 9912.  It's part of a large family of chips which seems
to be widely supported, if the advertisements of those selling them,
or, indeed, MOSChip themselves, are to be believed.  It's unhelpful that
many relevant areas of MOSChip's website seem to be accessible only to
corporate clients.

But how?  Finding hard facts on, say, printers is relatively easy, but
simple expansion cards seem to be largely ignored by the compilers of
compatibility lists.  If I want to spend $100 I can buy a branded,
well-documented expansion card which would undoubtedly work, but, by
following that route, I'd probably end up paying more for the simplest
of cards than I paid for the motherboard!

Despite my attempts to buy a card which uses a "supported" chip, I've
come unstuck.  I'm surprised, if it ever worked, that there's no sign
in linux-land of anyone who's actually using one, and has the knowledge
and skills to keep the drivers up to date.



[1] Actually parport_pc does something, although it's not very useful.

My copy of Mandriva seems to be capable of supporting up to four
parallel ports, /dev/lp0, dev/lp1 ..., and, if I try something like
"cat SomeFile >/dev/lp0" (lp1, lp2, lp3), it tells me "No such device
or address".

After loading parport_pc, "cat SomeFile >/dev/lp0" does nothing: no error
message, but no print.  OTOH "cat SomeFile >/dev/lp1" sends the file to
the printer, while lp2 and lp3 still produce the error message.

But I still can't configure a printer on that port.
