Today I took the whole lot to work to try it on a real rs232 port and it was a success. Well, out of a few attempts it only got as far as sending/outputting text once but that precious log is now here (see below - it's only slightly corrupted, presumably because of the absence of hardware handshaking). Failure to work with USB dongle is damn curios esp. since the same dongle works with other stuff. I had similar experiences before when two serial ports which were on margin of tolerances didn't want to play together nicely or at all. Who knows... Anyway, the main stuff... could it be that the interrupt problems it mentions early is to blame for all unpredictability and later mmc failures?
