I was looking over the data sheets for the 16550a Uart, and I noticed that
there is a DIP version of the chip as well as the more common square chicklet
packaging.
  Does anyone know if the pin-out on this chip is the same as the pinout of
  the older 8250 chip?
I have a serial card that uses an 8250 and I would like to use the 16550a 
so when I run DeskView the serial chip isin't chewing up all the processor
time.  has anyone plugged the 16550a into a 8250 socket on a serial card?
  
  Thanks,
