Now you really have me interested - thanks!

I've just spent a few hours tracking down an obscure (and intermittent!) 
bug in a script that controls a serial device only to find that it's a 
firmware bug, and I don't think that there's a way around it once it gets 
into that state without power-cycling the thing :-(

I'll fix the fundamntals before I get the flashy stuff working, of 
course...
