SerialPort not receiving any data

Question

I am developing program which need to interact with COM ports.

By learning from this Q&A: .NET SerialPort DataReceived event not firing, I make my code like that

Answer 1

I have never worked with VSPE so I'm not sure if that causes the problem. I have worked with a COM port before and I looked up my code. The only main difference is the way you declare the event. You have:

ComPort.DataReceived += OnSerialDataReceived;

I have it like this:

ComPort.DataReceived += new SerialDataReceivedEventHandler(OnSerialDataReceived);

OnSerialDataReceived is your eventhandler. I'm not sure if this will make any difference, but you can try it. I hope this helps!
