end;
...

in Delphi . the above code dont work in win XP , but work correctly under win 95/98/ME .
I will be thankful of you , if guide me with a sample source code.

You need some kind of driver or module. I know a hardware programmer who had the same prob. And he found some kind of module. Sorry but that is all I know. Hope i helped a little.
