How to Download and Install Port95NT.exe for 64-bit Windows
Port95NT.exe is a device driver that allows direct access to the parallel port from user-mode applications. It was developed by Scientific Software Tools and discontinued in 1999, but it still works on Windows XP and Windows 7. However, installing it on 64-bit Windows requires some extra steps. Here is how you can download and install Port95NT.exe for 64-bit Windows.
Download Port95NT.exe from one of these sources:
Right-click on Port95NT.exe and select Properties.
Click on the Compatibility tab and check the box for \"Run this program in compatibility mode for:\".
Select \"Windows XP Service Pack 2\" from the drop-down list and click OK.
Run Port95NT.exe as an administrator and follow the instructions to install it.
Restart your computer and enjoy using Port95NT.exe for your parallel port applications.
Note: If you get an error message saying \"DLPORTIO.SYS is not loaded\" when you try to use Port95NT.exe, you may need to manually copy DLPORTIO.SYS from C:\\Program Files\\DLPortIO to C:\\Windows\\System32\\drivers.
Why Use Port95NT.exe
Port95NT.exe is a useful tool for anyone who needs to control the parallel port from user-mode applications. For example, you can use it to backup video games, program microcontrollers, or interface with external devices. Port95NT.exe provides a simple DLL (DLPortIO.dll) that you can call from any programming language that supports DLLs, such as C++, C#, Visual Basic, or Python. You can also use Port95NT.exe to test the parallel port using a graphical user interface.
How to Use Port95NT.exe
To use Port95NT.exe, you need to include DLPortIO.dll in your project and link it to your application. You can then use the functions exported by DLPortIO.dll to read and write data to the parallel port. For example, you can use DlPortReadPortUchar and DlPortWritePortUchar to read and write a single byte to the parallel port. You can also use DlPortReadPortUshort and DlPortWritePortUshort to read and write a 16-bit word to the parallel port. You can find more information about the functions and their parameters in the DLPortIO.h header file.
To test the parallel port using Port95NT.exe, you can run TestIO.exe from the C:\\Program Files\\DLPortIO folder. This will open a window that shows the status of the parallel port pins and allows you to change them manually. You can also use TestIO.exe to monitor the data sent and received by the parallel port.
What are the Limitations of Port95NT.exe
Port95NT.exe is not a perfect solution for parallel port access. It has some limitations that you should be aware of before using it. For example:
Port95NT.exe only supports the standard parallel port (LPT1) at address 0x378. It does not support other parallel ports or addresses.
Port95NT.exe does not work on 64-bit Windows 10. You may need to use a different driver or a virtual machine to run Port95NT.exe on Windows 10.
Port95NT.exe may cause conflicts with other drivers or applications that use the parallel port. You should disable or uninstall any other parallel port drivers or applications before using Port95NT.exe.
Port95NT.exe may not work with some parallel port devices that require special protocols or timings. You should check the compatibility of your device with Port95NT.exe before using it.
How to Troubleshoot Port95NT.exe
If you encounter any problems with Port95NT.exe, you can try the following steps to troubleshoot them:
Make sure you have installed Port95NT.exe correctly and restarted your computer.
Make sure your parallel port device is connected properly and powered on.
Make sure your parallel port device is compatible with Port95NT.exe and does not require any special drivers or software.
Make sure you have the latest version of Port95NT.exe and DLPortIO.dll from the official sources.
Make sure you have the correct permissions to access the parallel port. You may need to run your application as an administrator or change the security settings of the parallel port.
Make sure you are using the correct functions and parameters to access the parallel port. You can refer to the DLPortIO.h header file for more information.
Make sure you are not using any other drivers or applications that may interfere with the parallel port. You can use TestIO.exe to check if the parallel port is working properly.
