I'd dearly love to know what's going on here. I could implement a kind of ~exponential back off where we wait 5 seconds, 1 minute, 5 minutes between attempts to reset the port?
Maybe Dave has some thoughts. I haven't played around enough with that stuff to have a very informed opinion, but that does sound worth trying on the surface.
I'm not completely sure what's going on, but I know that essentially when it happens you have to power cycle the board to get back to it. One thing I haven't tried as yet is to reset the serial port when it's stuck like this, but next time it happens I'll play around a bit more, rather than just doing a quick fix to get the board back online.
