Best way IMHO is to use a serial port component. Several versions are 
discussed in my thread:
"Serial port component, ComDrv32 vs SerialNG"
which was posted in May

These components have demo applications which act as terminals with full 
duplex capability. See:

http://www.torry.net/pages.php?id=198
http://sourceforge.net/projects/tpapro/
http://sourceforge.net/projects/comport/

Have a look at the source code and try the demos on your hardware to see 
what works best for you.
