16000000 inst/s   / 4800b/s = 3333.333... inst/b ...

The mistakes (all mine - must stop dividing my attention so much :) are that 
1bit @ 4800 is 0.2ms... and I kept saying BTYE, when my calculations were for BIT.

So, the new timing is:
        16,000,000 / 4,800 = 3,333.33..
        3,333.33.. * 8 = 26,666.66.. instr/Byte

Appologies to the OP, but the result is the same.  You will likely have ample 
time to parse the buffer

I agree, but that's said without knowing quite how complex the robotics 
control system is.
