Ik heb het zelfde probleem gehad.
zie topic: [topic=195589/1/40]
En dat heb ik opgelost door een ander i/o proggie te gebruiken.
namelijk USERPORT , Hier kan je dus zelf het adress van je lpt poort ingeven.
even knip en plak :
UserPort.SYS is a kernel mode driver for Windows NT/2000 that gives usermode programs access to I/O
Ports.
This makes it possible to access hardware directly from a normal executable in the same way as under
Windows 95/98/ME.
This driver does not work on Windows 95/98/ME and there is really no need to run it
anyway because I/O ports are always granted to usermode programs on these operating systems.
The driver can be used for the following purposes:
· To run software on Windows NT/2000 that normally only runs on Windows 95/98/ME.
· To easily access hardware like the parallel port and other I/O ports.
en werkt ook onder XP.
