What is RS-232?

RS-232 is typically used for inexpensive, relatively slower communications over short distances. It was originally introduced by the EIA in 1960 and is the oldest common standard for serial communication. RS-232 is still in very wide use today. The RS-232 standard includes one transmit wire, one receive wire and a single reference ground for transmit, receive and all hardware control signals
