My understanding (and experience) is that serial does quite well, but your 
maximum baud drops as you increase distance.  I don't have the numbers handy, 
but at a job I had in southern CA, we ran quite a distance at 9600 buad (not 
quite 30 meters, though).  Someone somewhere should have the actual figures.

I've been able to user serial cables of ridiculous lenths (certainly 30m)
working with PCs in our lab with no problems, and that was with various
gender changers, crossover boxes and the like. I was told by a technician
that the RS-232 spec allows for a wire length of up to 100 feet, but in
practice one can make them much longer.

I've used around a 20 meter cable between a 500 and 4000/030 for stunt car
racer etc. and i've not had any problems.

While in college, my roommate and I put together a couple of quite long
"dumb" null modem cables.  What I mean by that is they were only three wires
(transmit, receive and ground) with no hardware handshaking wires in them.
One of them was 100 feet long and we could achieve 115,200 baud with it.  The
other one was 250 feet long and, because of it's length, we had to lower the
baud rate to 57,600.  Quite good for such a long cable!

Anyone answering this Question, if you have heard of a null modem cable 
(not Parnet cable) for the Parallel port with a 25 male-male pin 
configuration please let me know. Olso if yes is there an amiga program 
to run this type of null modem?

Aloha! Richard
