I have just tried Waffle with 9600 baud and the X00 fossil driver
on a 8 Mhz XT and noticed that the UUCICO slowed from 800cps down
to 400cps with the fossil driver.  I have since removed the fossil
and am using the native driver again.  I get a few bad header errors
but the speed with these errors is still double the speed while using
the fossil driver.  I guess it's just not enough clock cycles available
for the fossil to work properly.
