    Hi all, I've spent many hours searching this forum and learnt a lot by doing so!
    However - now I'm stuck and I need expert help for something probably very basic.

    I just want to send a serial test output signal from Game Dash to my Arduino Uno board to see if they can communicate.

    I'm trying to build a wind simulator for Assetto Corsa, using the Arduino and a motor shield to drive a 12V PWM-fan. I've followed excellent guides from mainly SilentChill, but I'm using a different motor shield than him.

    So before I try to get it working with AC, I just want to test an output signal from GameDash to the Arduino, using the output test function for Dash1, setting it to a value of 127, making the LED on the Arduino half lit. Setting the output value to 255 making it fully lit.
    But I have no clue how to write or modify the Arduino code for this.

    I've got Game Manager and Game Dash setup for Assetto Corsa, so the speed is mapped correctly to the Game Dash <Dash1>
    I think I've got the connections settings right: COM3 (for me) - 9600 baud - 8 bit - NP - 1 stop bit.
    But I seem to get nothing over to the Arduino from Game Dash.

    I'm using a modified Arduino code that is provided by SilentChill, so when I'm in the Arduino Serial Monitor and type S255 the fan spins at full speed, so the connection works there. But nothing from the Game Dash.

    Anyone got a clue?
