You can frig the thing to do 76.8 (change from div 64 to div 16 - you
*might* be even able to use div 1 for tx though not for rx) - I don't know
how you're doing it but writing directly to the port (try not to use
irqs at all, poll for tx/rx in a tight loop) would help a large amount.

Hmm, will a PC do 76.8 ? Else you'd have to use 9600x4 = 38400.

Though that is a more practicable idea ...
