StandardFirmata on Arduino Due

Projects Interfacing w/ Software on the Computer

Please help me getting StandardFirmata to work on Arduino Due.

I use Arduino IDE 1.5.6-r2. The StandardFirmata Example compiles successfully. I program it to Arduino Due via the Programming Port.

Then I try to connect to it with firmata_test.exe from firmata.org. Which usb port of Arduino Due should I use? Both do not work. firmata_test always shows an empty window.

I also tried to toggle the LED on Pin 13 with Rhyduino or Sharpduino, it does not work at all.

According to Main Page - Firmata it should work.
What is the problem?

OK, it works with Firmata.NET from http://www.imagitronics.org/projects/firmatanet .
Use the "programming port".
firmata_test.exe from http://firmata.org still does not work.
Thank you very much for your time.

using Firmata.NET;
namespace FirmataNetExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Arduino arduino = new Arduino("COM10", 57600, true, 0);
            arduino.pinMode(13, Arduino.OUTPUT);
            do{
                arduino.digitalWrite(13, Arduino.HIGH);
                System.Threading.Thread.Sleep(750);
                arduino.digitalWrite(13, Arduino.LOW);
                System.Threading.Thread.Sleep(250);
            } while(true);
        }
    }
}
