Oops, my bad. I meant to say RS422 or RS422/EIA422 to be picky.

For our listening audience RS485 is a close cousin. You can use a pair of RS422 circuits to implement a 'full-duplex' channel or use RS485 to implement a 'half-duplex' channel.

Since we are here:

RS232 is single ended, RS422 is differential. What does that get you? long distances and noise immunity. Very useful in the electrically noisy environment of a student built robot.
