Beware of the errata sheets though. For instance, on the 16C74 you're adviced not to use a certain baudrate setting mode. For the other 16Cxx devices, get application note AN555, "Software Implementation of Asynchronous Serial I/O", document DS00555B on the Microchip website. It gives you both sample schematics and a lot of code. Good luck Michael
