The cable is a standard "parallel null modem" variety also used with
Norton Commander and Windoze95 parallel port link. It is sold in computer
shops in US under the name "interlink cable".

Now, to the more important question: when will it be possible to limit
amount of CPU time taken by PLIP driver? Doing direct transfer between the
gateway and the PLIPped host now takes 100% of CPU time, meaning
everything else hangs on both these machines. It becomes a little bit
easier when you run some high-CPU-consumption program (GCC or an
interpreting emulator of another computer do just fine) concurrently with
the transfer, but is there a decent way to control that?
