Visual C++ serial communication problem

[Tazye]

I developed a Visual C++ 6.0 application which is using the serial communication. It works fine under Win98 or Win98 but the communication is not working at all under Win2k or WinXP.

Does anyone encountered the same problem? If somebody knows what's all about, a quick answer is appreciated!

Did you use the proper win32 API, using CreateFile()

Or did you use some low-level device access using something like inport(), or direct access to the hardware.

In short, post some code, and please use the [code][/code] tags.
