The actual RS232 serial data is handled by a UART function in the Paula Chip,
not the 8520's.  The serial keyboard interface is handled by serial port on
one of the 8520's, the other 8520's serial port is available on the parallel
connector.  Is this confusing enuf 8-)

The Paula serial port deals with Asynchronous data formats, while the 8520's
have separate clock and data lines.
