Serial Com Terminal on Windows CE
Hello!>>
I�m writing an Application that I created in Visual C#. The application is
a Serial Com Terminal. I want this to run as a Windows CE Application in my device emulator. But it�s doesn�t really work. I don�t� have any error but I can�t send other received any message from the serial port.
Can anyone please help me out in this?
Thanks in advance
