I am a driver, I drive a Ford and stay on the road, yesterday I drove a Toyota and ran into the ditch. This is more descripotive than your post. NOBODY can help you based on what you wrote and i hope nobody will sabotage your debugging skills by responding to "give me one sample program". If you can not describe the problem in detail how do you expect anyone (including yourself) to solve it. u all seems contradicory 'micro' is small and 'all' is big. Erik
Have you tried the example interrupt driven serial program located here? http://www.keil.com/download/list/c51.htm
