Hi I'm trying to connect a Serial output wheigher to Netduino.

I buy a TTL shield and connect it to Netduino 1.
My first problem is, when I connect My netduino to USB port my PC create/reserve a COM port for the Netduino comunication, and then when I connect the rs232 shied to Neduino my PC must ce create/reserve another COM port for this shield?

 

Because I dont understand how in a lot of code I found this:

 

  SerialPort mySerialPort = new SerialPort("COM1");

  mySerialPort.BaudRate = 9600;
  mySerialPort.Open();

 

How I can be sure that my shield assume the COM1 ?

When I connect my shied to netduino nothing appear on the screen

 

thanks
