/************************************************************************-

EVA Board:

    EVA300-3


Input PIN:

    ADIO_6       for UART communication


Output PIN:

    ADIO_7       for UART communication

    SCSEDIO_0   indicates that an telegram ERP1 was send/received

    SCLKDIO_1   indicates that an telegram ERP2 was send/received


Description:

    This example demonstrates a serial (ESP3) gateway. All the radio telegrams that are received

    from the AIR are sent to the UART and vice versa, all serial telegrams that are

    received from the UART are send to the AIR.


Notes:

    The return values of the radio_senTelegram are not checked!


    The incoming radio telegram parameters pTel ARE transmitted through the UART!
