I am running both Crosstalk and WinComm at 19200 using a Courier HST 
modem.  The machine is a 55sx with a 16550 chip and the Comm Driver
patched to allow rates higher than 19200.  (WinComm supports upto
115k.)

I do not lose characters while editing on a Unix host with Emacs.

Some characters are lost during high speed Zmodem downloads.  They
are buffer overruns caused by Windows inablility to service the
Uart fast enough.

I have ordered but not yet received a Windows Comm Driver which 
supports the 16550 buffers both for Windows Apps and virtualized
16550s in DOS Shells.

I will post to the net when I receive it.
