We're loosing serial bytes from PC to phone

Does the 16C750 do anything fancy to compensate for slow/fast clocks by
adjusting it's internal sampling points to the edges on the incoming data?

If he does, we might have a clock that's slightly off and the compensation
might fix that for anything except the 0-bytes which don't have any 0/1  
transitions.

To find out, one could use a lower baud-rate and adjust the divider until
the problem gets worse/goes away. And always check with a 2nd com-port on  
the PC
in parallel.
