On a Data General minicomputer I used to work on, it used RS232 cables and connectors
to connect the
computer to the terminals, at 9600 bps. I know that some of the terminals were
several hundred feet
away. However, we only used 3 wires of the cable, send, receive, and ground. So, if
someone only
wanted to use those wires, they could maybe go several hundred feet. I admit though,
that if you
wanted to also use the other signals in the cable, maybe you couldn't go as far, I
don't know.
Also, it's possible that a Desktop computer might not provide as many amps to drive
it, as the Data
General did.
