Hmmm, we can talk about doing something like that later on. But
just having port control is nice and sweet!

Which is why IEEE 1284 is still nice.

Now only if I could find a PCI parallel port card that has a Linux
driver. I haven't done much research, but I don't think many do.
Sure, I can get 2-port ISA cards for $27 so I can have 3 ports on a
box, but that's only good until ISA dies.
