     The UART for you is the TMS-1602.  This is the original, generic UART.
Strppable for any combination of word length, parity, stop bits, etc.

     BTW... why are you doing this this way?  Why not just set up the PC
serial chip ( an 8250 is sooo easy! ) with the parameters you need?
You can write an interrupt routine to run in the background so's you're not
watching the port all the time.
