FYI, I don't know if this data point matters, but...

I'm having no problems.  However, I'm using a slightly modified
version of John M Vinopal's latest snapshot of the Hayes ESP driver
(which is just a slightly modified current com.c).  Everything is
working just peachy with this com.c, my Practical Peripherals 28.8K
V.34 modem, and my Hayes ESP.

Also, my Logitech serial mouse is still working fine on a 16550 port,
but the mouse, I believe, only sends bursts of three or four bytes at
a time.
