SoftCollection Parallel Port Library For .NET download - Lets you a full control over the Parallel Port of your PC.

SoftCollection Parallel Port Library For .NET lets you a full control over the Parallel Port of your PC. You can set separately an electrical potential, 0v or 5v, on each writable pin, and you can get an electrical potential from each readable pin of the Parallel Port of your PC. The male-connector, that you connected to your PC Parallel Port's DB-25 female-connector, has 25 pins. These pins divided into four groups: 1. Data Pins (2,3,4,5,6,7,8,9). These pins may input (from outside) or output 0V or 5V, depending on the Mode (Read/Write). 2. Status Pins (10,11,12,13,15). These pins are readable only, and may only input 0V or 5V from outside. 3. Control Pins (1,14,16,17). These pins are writable only, and may only output 0V or 5V. 4. Ground Pins (18,19,20,21,22,23,24,25). You can for example: Connect a LED through 500 Ohm resistor to every pin, that may output signal (1,2,3,4,5,6,7,8,9,14,16,17). Connect a button through 500 Ohm resistor to every pin, that may input signal from outside (2,3,4,5,6,7,8,9,10,11,12,13,15). PLEASE REMEMBER YOU MUST CONNECT EVERYTHING THROUGH A 500 Ohm RESISTOR!!! OTHERWISE YOU MAY CAUSE HARM TO YOUR PC!!! You can use this library in C#, VB.NET and other programming languages supported by .NET.
