DriverLynx DLPORTIO and Windows 7

Dead link: DriverLynx PortIO (DLLPORT.SYS) is needed on Windows NT and higher to access the I/O ports in a PC from a program, for example in Delphi.

New location for download:

Working examples, including the driverlynx driver and with Delphi  example sources  are on my Programs and PC ports pages

Alas, Windows 7 (and Vista) make it a bit more difficult to install this driver.  It seems everything is allright running the installer (port95nt.exe), but running the program gives the error  DLPORTIO.SYS is not loaded.

But it can be done as follows:

  • Right Click Port95nt.exe
    – Properties
    – Run this program in compatibility mode for: Windows XP Service Pack 2
    – Run this program as an administrator

And now it does install and the program runs.

  2. Hello,
    is there a solution that also works with Windows 7 Pro 64bit?
    It refuses to install on my installation of Windows 7 64bit.
