We noticed your patch, and tried it out, however it does not affect 300 baud
communication at all.  We avoided the speeds you had problems with.

I will take a closer look at your patch soon.  It is not forgotten, it's
just that probably nobody else has a clue about it either, so we need at
least to reproduce the problem you saw and test your fix. ;)  But frobbing
the watermarks et al for higher speeds is likely to be necessary (as you
found out) to get a sane behaviour, so you can assume that I will check in
your patch shortly.

Thanks,
Marcus
