Port95nt.exe: A Handy Tool for Parallel Port Programming on Windows 7 32-bit
If you are interested in parallel port programming on Windows 7 32-bit, you may have encountered some difficulties in accessing the parallel port from your code. Windows 7 32-bit does not allow direct manipulation of hardware by user-mode applications, so you need a device driver to "talk" to the parallel port. One of the device drivers that can help you with this task is Port95nt.exe. Port95nt.exe is a free and open-source tool that enables user-mode applications to read and write data to the parallel port. In this article, we will explain what Port95nt.exe is, why you need it, how to download and install it, and how to use it in your code.

What is Port95nt.exe and what does it do?
Port95nt.exe is a device driver that was developed by Scientific Software Tools and was discontinued in 1999. However, it still works on Windows 7 32-bit and can be used for parallel port programming. Port95nt.exe provides a simple DLL (DLPortIO.dll) that you can use in your code to access the parallel port. The DLL exposes some functions that allow you to read and write data to the parallel port registers. You can use these functions with various programming languages such as C++, C#, Visual Basic, etc.
The parallel port is a type of interface that can connect devices such as printers, scanners, modems, etc. to a computer. The parallel port can also be used for programming and controlling external devices such as microcontrollers, LEDs, motors, sensors, etc. The parallel port has three registers: data register, status register, and control register. The data register is used to send or receive data to or from the device. The status register is used to check the status of the device or the port. The control register is used to control the direction and mode of the data transfer.
Port95nt.exe allows you to access these registers from your code using the following functions:
DlPortReadPortUchar: Reads a byte from a specified port address
DlPortWritePortUchar: Writes a byte to a specified port address
DlPortReadPortUshort: Reads a word from a specified port address
DlPortWritePortUshort: Writes a word to a specified port address
DlPortReadPortUlong: Reads a double word from a specified port address
DlPortWritePortUlong: Writes a double word to a specified port address
For example, if you want to read the data register of the parallel port (which has the address 0x378), you can use the following code:
#include "DLPortIO.h"
unsigned char data;
data = DlPortReadPortUchar(0x378);
// do something with data
If you want to write the data register of the parallel port (which has the address 0x378), you can use the following code:
#include "DLPortIO.h"
unsigned char data;
// assign some value to data
DlPortWritePortUchar(0x378, data);
Why do you need Port95nt.exe for Windows 7 32-bit?
You may wonder why you need Port95nt.exe for Windows 7 32-bit when there are other device drivers or tools that can access the parallel port. The answer is that Port95nt.exe has some advantages over other alternatives. Here are some of them:
Port95nt.exe is free and open-source. You don't have to pay any fees or licenses to use it.
Port95nt.exe is simple and easy to use. You don't have to deal with complex installation or configuration processes.
Port95nt.exe is compatible with most parallel port devices and applications. You don't have to worry about compatibility issues or conflicts.
Port95nt.exe is reliable and stable. You don't have to worry about errors or crashes.
Of course, Port95nt.exe also has some limitations and drawbacks. Here are some of them:
Port95nt.exe is outdated and discontinued. It may not work on newer versions of Windows or with newer devices.
Port95nt.exe is not supported or maintained by anyone. You may not find any help or updates if you encounter any problems or bugs.
Port95nt.exe may not be legal or ethical in some situations. You may violate some laws or rights if you use it for unauthorized or malicious purposes.
Therefore, you should use Port95nt.exe at your own risk and responsibility. You should also respect the work and effort of the original developers and authors of Port95nt.exe.
How to download and install Port95nt.exe for Windows 7 32-bit for free?
If you want to use Port95nt.exe for Windows 7 32-bit, you need to download and install it on your computer. However, you need to follow some steps to make sure that the installation is successful and safe. Here are the steps to download and install Port95nt.exe for Windows 7 32-bit for free:
Download Port95nt.exe from a reputable and secure source. We recommend OSDN, which is a platform that hosts open-source software projects. You can download Port95nt.exe from OSDN by going to https://osdn.net/projects/sfnet_ucon64/downloads/ucon64misc/ucon64misc/port95nt.exe/ and clicking on the link that says "port95nt.exe (external link: SF.net)". Save the file to your computer.
Scan the file with an antivirus or anti-malware program. Make sure that the file is not infected or corrupted. You can also check the file size and MD5 checksum to verify its integrity. The file size should be 1,648,426 bytes and the MD5 checksum should be 59e45c204d2a5e25d7662d96abf4d594.
Run Port95nt.exe as an administrator. However, before running it, you need to change its compatibility mode to Windows XP Service Pack 2. To do this, right-click on Port95nt.exe and select Properties. In the popup window, click on the Compatibility tab. Check the box that says "Run this program in compatibility mode for:" and select "Windows XP Service Pack 2" from the drop-down list. Click OK.
Follow the instructions on the screen to complete the installation. The installation will create a folder called "DLPortIO" in your Program Files directory. This folder will contain only the Windows uninstaller. The actual files that you need are DLPortIO.dll and DLPortIO.sys. DLPortIO.dll is the user-mode DLL that you can use in your code to access the parallel port. DLPortIO.sys is the kernel-mode driver that enables this access. These files are installed in your Windows\System32 and Windows\System32\drivers folders respectively.
After installing Port95nt.exe, you can start using it in your code to access the parallel port. You can also uninstall it if you don't need it anymore by running the uninstaller in the DLPortIO folder.
How to use Port95nt.exe in your code?
Once you have installed Port95nt.exe on your computer, you can use it in your code to access the parallel port. You need to include the DLPortIO.h header file in your code and link with the DLPortIO.lib library file. You can find these files in the DLPortIO folder or in your Windows\System32 folder.
You can use the functions provided by DLPortIO.dll to read and write data to the parallel port registers. You need to specify the port address and the data value as parameters. The port address depends on your parallel port configuration and device. The data value is an unsigned char, unsigned short, or unsigned long depending on the function.
For example, if you want to read the data register of the parallel port (which has the address 0x378), you can use the following code:
#include "DLPortIO.h"
unsigned char data;
data = DlPortReadPortUchar(0x378);
// do something with data
If you want to write the data register of the parallel port (which has the address 0x378), you can use the following code:
#include "DLPortIO.h"
unsigned char data;
// assign some value to data
DlPortWritePortUchar(0x378, data);
You can also use other functions such as DlPortReadPortUshort, DlPortWritePortUshort, DlPortReadPortUlong, DlPortWritePortUlong, etc., depending on your needs.
