    first make a program that what ever you send from the PC terminal, it should be sent back by the controller to the PC…. known as loop back… here is the link…

    if this one is working it shows that the controller is receiving the data that you have sent…

    by the way what did you send from the terminal… i mean don’t send numbers…
