I want to where I can get help to have my philips 89C664 microcontroller to communicate to an RS232 port....
Look in the support section for the examples & application notes - these will give you examples of the software part. You will also need hardware (transceivers) to interface the uController's 5V port signals to RS232 levels; eg, Maxim: http://www.maxim-ic.com/
oops - I forgot to add that the Philips site also has an extensive collection of examples & application notes
