TS, I've just given your latest version a quick try but the files generated don't seem to load from the XP netbook any more the way the ones from the previous version did.

Have you changed the data rate by any chance? Audacity shows that the silent lead-in time is just under two seconds, was that the interval you intended? I'm wondering if the whole file has been generated a bit too 'fast'.

The machine is loading code and it loads it exactly the same way every time, but wrong.

The first byte (should be 'C4') loads as '04' - the LSB of the byte is received first by the MK14 and the MSB last, so it looks as though it is loading the lower nibble of the byte OK but then going out of sync by the end of the byte.
