Myles,
What do you mean by quit? My 830M boards just quit/stop/halt at certian 
points (seems to always at same places) also with the recent versions of 
serialice. They used to work great with the first publicly released 
versions of serialice. If I cycle the power real quickly it continues 
on. I am not sure what changed but if this sounds like your problem too, 
try a earlier version. I am curious to hear your results.
