#X text 32 16 To get it running under WinNT/2000/XP a special kernel
driver is needed. These systems do not allow direct access to I/O ports.

#X text 53 207 If you ever whish to remove the kernel driver start
the programm again and click 'Stop'.;
#X text 54 242 Under Win95/98/Me all this is not needed!!!;
#X text 52 272 Good Luck!;
#X text 54 141 The subfolder 'UserPort' contains a kernel driver that
handles the I/O stuff. Just copy the file UserPort.sys into %WINDIR%/system32/drivers
(e.g. C:/WinNT/system32/drivers) and run the program UserPort.exe.
Click on 'Start' and then 'Exit'.;
