1.	Serial Protocols Compared TIA/EIA-232-F (typically referred to as RS-232) is a common interface that can be found on almost every personal computer. RS-232 is a complete standard, not only including electrical characteristics, but physical and mechanical characteristics as well, such as connection hardware, pin-outs, and signal names.

2.	Introduction to Interrupts When a device asserts its interrupt request signal, it must be processed in an orderly fashion. All CPUs, and many devices, have some mechanism for enabling/disabling interrupt recognition and processing: URL: http://www.embedded.com/story/OEG20010518S0075
3.	Synergy cross-computer keyboard/mouse use Synergy is FOSS that lets you easily share a single mouse and keyboard between multiple computers with different operating systems, without special hardware. All you need is a LAN connection. It's intended for users with multiple computers, where each system uses its own display. URL: http://synergy-foss.org/

Introduction to Stepper Motors I am by no means an expert on stepper motors. I have not completed my education, so I do not know all of the mathematics or mechanics that go into the design and operation of stepper motors. What I do know is what I have learned from my experience with these electro-mechanical wonders. This document willout line sources that carry stepper motors and how to control them manually (with discrete logic), with a microcontroller, and with computer control.
