	I've experienced similar problems as well (although they aren't
	happening as often now). But I never had the patience to sit and
	wait to see if the port ever came back to life even for a
	moment. 

	I had noticed that this generally happened when two precesses
	tried to grab the port at the same time, or even when the port
	was being used, and your UUPOLL script (wonderful script BTW)
	tried to access the port.

	I did some minor changing to your script to abort if it found
	ANY LCK file (since I only have one line) and things seemed to
	have cleared up. 

	Chances are, we are looking at two different problems though. Oh
	well, I tried.
