This article will demonstrate how to use your 50g to control your
Windows/XP keyboard and mouse. Examples include:

1. Simple data entry.
2. Multiple cell Excel data entry.
3. A plotter application.
4. Interactive mouse control.
5. Controlling EMU48.

This automation is achieved with SerialKeys. SerialKeys is a serial
port keyboard and mouse interface primarily used as an accessibility
feature. Although this article targets the 50g and Windows/XP, it
should be trivial to repurpose for any 48/49 and for OS/X and Linux.
