This article describes the differences between RS-232 and TTL, and how to build a converter that can connect a Microcontroller to an RS-232 compatible device, such as the COM port on the PC.
This site has a good description of how to do a hardward converion for a cable connector. I spent about 10 minutes browsing the site. The content is good with photographs and drawings to describe the electronics used in the conversion. This is a good addition to a course about cabling systems. The materials were easy to use, since it is simply an html site.
