    This is a SerialPort question according to your description. I would like to move your thread to .NET Framework Class Libraries forum to get more response.

    Thanks for your understanding and support.

  • your code looks fine, however just confirm the wiring of the device attached to serial port.

    TLP-> can you explain on this.

  • I agree with RohitArora. Your code looks OK except for a minor detail. When you use Invoke (instead of BeginInvoke) remember to close the port from a different thread to avoid a possible deadlock as explained in chapter "SerialPort Receive" of my SerialPort tutorial.

    Besides, since you only use the standard delegate (EventHandler) to "wake" a method on the UI thread and doesn't need information about the caller, you can optimize your code a little by using the standard delegate MethodInvoker instead.


    Everything should be made as simple as possible, but not simpler. Any fool can write code that a computer can understand. Good programmers write code that humans understand.
