Mike,

I found this website to be very helpful.
http://www.robmeerman.co.uk/project. Download the report disc content, and
look for the source code for the serial interface. It tells you how to put
the serial port into multi-purpose mode, and set each of the 4 digital lines
to the values you want. You'll need to write a function that reads the
states of the digital lines.
