Hi All, I was wondering if anyone has had any success in getting some of the examples to work from this book. I am attempting to get the examples for onboard usarts (16c63) working, and have had no luck. The circuit diagram in this text uses 6 lines, TD, RD, DTR, RTS, GND and COM. I would like to be able to just use TD,RD and GND. If no-one has used this book/example, can someone recommend an example that will work with the on-board usart of the 16c63?? Thank you for all your time and help. --|\/| | |< E The most exciting phrase to hear in science, the one that heralds new discoveries, is not "Eureka!"
