   How long after the path gets broken does it occur? I have nothing 
attached to the serial port yet. I'm wondering if that is the problem. I 
would hope that things would be written such that if a port became 
non-responsive the system would not chew up CPU.

I wish I knew C better, I'd go trawling through the code to see...
