But how is the byte acked? What happens with modems? If I hook up a
modem, the round trip will probably exceed that 2 ms due to compression
and other stuff. We are after all talking about almost 4 byte-times.

But if it needs to re-synchronize, it would tell me, right?
It does not say anything about sync...
(Hmmm, see the debugging commented out, recompiling...)

Well, another good solution would be a real power-boot :).
