	I have two COM ports in my computer (386/20) now with 8250 UARTs in
them, what advantage if any would it be to upgrade to a 16550 UART? My 
setup is as follows:
   - 2 Serial ports
   - On COM 1 I have an external 9600baud modem
   - On COM 2 I have a mouse
   - I have a 386 20Mhz with a 6mb on memory
   - My telecommunications program mentions support for 16550 FIFO buffer

	In the past I've run my serial ports at up to 115,200 baud during
serial connections to another computer, so what advantage could this better
UART hold for me? What is the idea behinf the FIFO Buffer, I understand it
has to be enabled & disabled which would mean it's not something Automatic,
does that mean it's not always good to use it? If a program doesn't support
the 16550 UART specfically, can it still use the COM port?

Thanks for any help, sorry if the subject may be wrong.
