You've missed the point. The sio overflow problem isn't caused by
data coming in too fast. The sio buffer just isn't flushing, it
seems. I did try a slower speed initially but it doesn't matter what
speed it runs at; if the buffer isn't flushed, the next nugget of data
that comes in from the port overwrites what's sitting in the buffer
and thus the sio overflow.
For reference, this serial port is connected to an ISDN TA and is
often doing a 2B (128k) connection to my ISP.
