    Connecting the micro controller with the PC serial port interface


    Hi..

    I am recently work as a Research Assistant and doing a project named Prediction
    From NDT - Direct Stress Measurement.

    I'm looking for a solution for my project.. the first part of implementation
    of the interface circuit for this project is already finished which is the
    PC serial port circuit. But i'm having a problem to connect the finished
    circuit with the micro controller to send and receive data from micro ohmmeter;
    which I connect it to the micro ohmmeter. ( the micro ohmmeter is connected
    to the micro controller )..

    I have tried to find the suitable circuit but it seems like doesn't work.
    I am greatful if any of you could give me an idea with this problem.. Thank
    you very much !!
