Port RS-232 App from VC++ to EVC++

[D002199]

I have a COM port app wrote in VC++ which running fine under Windows NT/2000/XP.
Recent day I tried to port it to Embedded VC++ 3.0 which will run on Windows CE 3.0.
Compile & link no any error, but it can not successfully open the COM port.

What's wrong? any idea?

Thanks & Regards

Is the com port configuration the same? Have you played with the configuration settings? parity, baud, etc...?

What kind of old WinCE device is it that still has a COM port and not USB ?
