    Passing a handle between processes

    Hi,
    I am researching if it is possible to pass a handle to the serial port to another process. If I have process A that opened a handle to the serial port and then process A forks a new process B (If even possible) by calling an execultable on the hardrive. Can process A pass the handle as a command line argument to process B or maybe put the address in the registry where process B can access it. Thanks
