Hi, i got assigned some hw about the RS 232 interface. The assignment is:

You are asked to write a technical note to teach people to use the rs 232 for electronic communication between devices. Include in your note the basic set up, a description of the interface including possible ways to present data, and give an example for a printer connected to a computer.

Can someone help me with this? I am reading online and there does not seem to be anything that is giving me the information the way i need it.
