If you want to make best use of the extended buffer, you'll want to make sure
that you set the COM port to BUFFER=ON rather than AUTO.  If BUFFER is AUTO,
as long as IDSR and OCTS are ON (the default, and probably good to do), you'll
still be getting 1 interrupt per character even with the 16550's.  The other
settings shouldn't have to change.

For some detailed info, check out a post I made to this group on 9/3 (if it's
gone from your server, drop me a note and I can send you a copy).
