After some more tests I am consistently seeing around 580 cps on a
direct 9600 baud line between a uVax running VMS and a 68000 Unix
box.  Windows=7 PKTSIZE=64.

I have never seen 90% bandwidth utilization.  My 3B1 at home running
at 1200 baud always gets around 100-120 cps.  How are you computing
bandwidth utilization?

(c * 8) / b

where b = baud and c = chars. per second?
