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
Chinco
