At least the older Xircom adapters can work in nybble-mode with a uni-
directional port. I just didn't think they'd break it with the newer
models. I want a PE3, not PE2 because of power consumption - the PE3
can be powered off of a parasitic cable (typically from the keyboard
jack, but there isn't one on an XT laptop; I was just going to wire
one in). There are parameters you can tell the PE3 to use when connecting
the driver, but I'd have to look them up; I haven't actually used a
parallel port adapter since I was at McMurdo.

AFAIK, there will never be any newer drivers because Xircom isn't forthcoming
with their internals details. I tried for a long time to get info out of
them so I could adapt a PE3 to the Amiga, but they formally rejected my
written propsal because they didn't want to be in anything but the DOS market.
Since then, they've been more flexible, so the newer PCMCIA Xircom NICs work,
but I have this CE-10BT that only works under older stuff (fortunately, I do
happen to have a PCMCIA NIC or two that _is_ supported under Linux; my
CE3B-100BTX the only thing I have for the laptop that will go 100Mbps and
isn't Cardbus).
