Reading all the talk about 16550AN UARTs in the DSZ and Qmodem
documentations, I decided to go out and get one.  However, my serial card
doesn't use UARTs; it uses a VLSI chip.  Questions:

1) What is the difference between a UART and a VLSI chip?  (Qmodem tells me
   I have a 16450...)
2) Is there a pin-compatible replacement for the VLSI that has a FIFO
   buffer?  I use Desqview for everything I do, and when downloading at
   19200 baud in the background, I get a ridiculous number of errors.

Thanks.
