Subject: 8051 Interrupt Driven Serial Port, Internal Memory, Dallas Processors
 
        Here's a interrupt driven serial port driver for a Dallas
80C320 using the second serial port.  It uses internal memory for the
buffers, which can be up to whatever space is left over after the
stack and other internal variables.  The routine assumes that Timer
0 or Timer 2 has already been setup to the appropriate mode and rate.
Currently, the serial port is setup for Mode 1, which is what's used
for the 8/N/1 format.
