Introduction to parallel port (LPT) interfacing


Warning!:Usage of parallel port without care may cause serious impact on your PC.

Nowadays programing parallel ports (also known as printer port LPT (DB25 female on the back of IBM type PC) are prone to disappear from newer PC's. But, as far as computer based control engineering is concerned, parallel port is the easy way. So many people stick on parallel port. There are a plenty of programming languages offers convinent control over parallel port by high leve l of abstraction.In order to control things through your parallel port,you need a simple hardware also. Don't need to buy, just build one in your home. Before you dig into parallel port, just know what is a parallel port. If you are confedent that you have some knowledge of parallel port, just skip the links below.

Assuming you acquired basic operation of parallel port. Now let's begin to dig. Here I tried to describe maximum of how to work with parallel port in different systems and different platforms. You can read all of them in posts tagged in Parallel Port.
