Hello everyone
i'm looking for help on writing C program that when started, it's counting time (like 10 seconds) and when any key is pressed (shoul'd be any key - all keys), start to count again. when the timer reached the 10 seconds and no key is pressed, the program send out data via the serial port (rs232) or even a beep to the speaker.

any help will be appreciate

TNX
