Nowadays, Winamp has full support to keyboard shortcuts. But some time ago, when Winamp didn’t have this feature, I was thinking of a way I could change the music just by pressing one button, it would make it faster and easier to change songs, especially during games. So I decided to make an external control to it. I found one Winamp plugin that shows how to configure an external control using the Serial Port, being able to make 4 or 15 buttons control. I decided to make this, step-by-step, how to do it, hope you enjoy.
