Does anyone know how to get this small chip to communicate with a serial port. All I want is a program that will send a simple character, like a 'a', through the serial port. I want this so I can build some kind of serial test for visual basic. If anyone knows can they please tell me, or can they give me an address of someone who will be able to help. I believe that I will have to connect a chip like a MAX232 between the computer and the microchip. Many thanks A Bevan Aib750@Bham.ac.uk
