FWIW, here's what my book (Upgrading and Repairing PC's, 12th
Edition) had to say about those - -

"The 8250B chip might work in an AT under DOS, but it does not run
properly at 9600bps because, like all 8250's, it has no transmit/receive
buffer."

16550A - "Use a version of this UART in your serial port if you do any
communications at 9600 bps or higher.  If your communications program
makes use of the FIFO - and all of them do today- it can greatly
increase communications speed and eliminate lost characters and data at
higher speeds.  Virtually all Super I/O chips contain the equivalent of
dual 16550A or later chips.  Most 16550 UARTS have a maximum
connumications speed of 115Kbps (bits per second)."

Good luck. - - - JimH.
