Now, it has already be mentioned that you'll need a crossover cable or
connect the computers via a hub. A hub or switch would be especially
nice at least to try if you get a connection, blinking lights are a
wonderful thing. Are both cards reporting link and activity if you,
say, send pings between the machines?
Two more things from my personal anecdote chest, both about strange and
more or less rare error conditions:
If comp. A's card is 10/100 and the PCMCIA card is 10Mbit only, try to
throttle the A card down to 10MBit. This should not be an issue, but
has caused me problems on older hardware that apparently couldn't
auto-sync.
Try using an unshielded cable to hook up B. Each and every PCMCIA card
that I tried refused to work with shielded cables (with shielded plugs,
you recognize those by the metal tongs on the side of the plug).
Unshielded cables (plasic-only plugs) worked perfectly.
