While I would normally agree with Greg, I have found that the callout device
solution works better (for me) than the uugetty approach. I'm not sure why,
but I really think it does (and I gather that I'm not alone).

Ugh. Only a solution if you have a breakout box or a cable-making kit. If
you're stuck at home with just a set of cables that have molded connectors, the
software approach is the only answer (I'd hate to tell people that the answer
to getting their terminal working is to buy a breakout box or make their own
