Hello Dave, If I transmit via the Windows buffering in a tone to the sound card, no problem. If I transmit through the serial port, I need to control the time ellapsed (for a dot or a dash). As under Windows there are no interruptions (sniff), there is no way to know at which moment is the end of the dot (or the dash). So I keep the CPU working in a loop, testing the Windows timer, until the end of the dot. It is not a very elegant method but I don't know an other way to do it. Note: the Delphi system timer is not sufficiently rapid (maximum between 20 to 60 /sec).
