This is a problem with inpout32.dll, my first thought would be to check that you are running on a 32-bit system. If you have Windows 7, you might try inpoutx64.dll available here: http://logix4u.net/index.php or just see if there is a newer version of the 32-bit DLL here: http://logix4u.net/parallel-port/16-inpout32dll-for-windows-982000ntxp I'm sorry that I can't really diagnose your problem much further than that. The makers of inpout32 know this stuff a lot better than I do. Good luck with your project.

Good luck with your project.

I figured I would try your program as well since we are using similar methods, and it gave the same error: Traceback (most recent call last): File "C:\parbufftest\portmon.py", line 126, in myframe = MainWindow(None, wx.ID_ANY, 'Parallel Port Monitor by Adam Pierce ') File "C:\parbufftest\portmon.py", line 73, in __init__ self.UpdateStatus() File "C:\parbufftest\portmon.py", line 97, in UpdateStatus d = ctypes.windll.inpout32.Inp32(0x379) WindowsError: exception: priviledged instruction Any ideas? User privileges maybe? Hi Adam,
