Hi,

I have no problem to write and read through my COM1 in my app which created
in Console based application.

So far I tried which are successful in pc win app, pc console app and smart
device console app.

Once I used the Win app in smart device, there is a problem. So, there
isn't any error message when I initialized the com port as shown below:

private SerialPort _serialPort = new SerialPort("COM1", 38400, Parity.None,
8, StopBits.One);

But, I couldn't get the response from my serial device. Is there any
special tricks to initialize com port in CF 2.0 Win App? Or it didn't support.

Thank you.

Try using a colon after the port name.

May be you need some other options like
DTS=ON ore DTR=ON
