    Hallo everyone,
    I have problem with communication over serial port.

    This is what I am having problem with:

    I need to make communication with device which has usb on rs232 convertor and fifo memory.

    I sent data to fifo memory in same time device read data from fifo memory.

    When micro (in device) sees that memory is full, it change state of CTS signal. CTS signal stays in that state until memory is half full.

    I have problem to write code in C that sends data to device but considering CTS.

    I send data as char byte array, memory is 4K , speed is 38400

    Does anyone have a clue how I can solve this mistery
