yesterday's changes (i.e. before rev. 1.10 of ser_posix.c), that is,
exit(1) in case of a timeout. Previously, the upper layers didn't see
the timeout at all.
Quite possible that some of these drivers could handle a timeout more
intelligently though. At least for the rather sophisticated STK500v2
protocol, I think it should be possible to retry the request.
