1) I don't know C well enough to be sure what is going on.
2) I don't know how to monitor it to be sure it is doing what I think it does.
Basically, I was hoping there was someone who reads this list who knows the
serial port well enough so I could tell them what I *think* is going on in
that routine and they could tell me if I understand it correctly or if I'm
way off.
It seems, though, that this is a very low traffic list.
