gdmux stalls after a varrying number of lines in a largish file #2

Example that stalls gdmux here: http://hastebin.com/kidoqijeve.avrasm

OK, it's worth trying a smaller baud rate. baudrate is an argument to gdmux now.

I've not seen this happen since we pushed down the baudrate and switched to synchronous moves. Did you say it crapped out once? Was is the same error message?

I'm not sure, can always test again!

Still happening. I can sort of reproduce it. I think this will be my mission for the next week.

So it's more likely to be the 5v USB line where the interference starts. Try running GDmux on asimov, if you can't reproduce the problem there than it's almost certainly due to the USB-Serial converters

This doesn't affect asimov with the hardware serial port. So it's either the USB serial adapter or something more sinister on the Pi.

I'll keep the issue open till that's sorted.
