The RS232 STANDARD The RS232 STANDARD, renamed the "EIA232 Standard" in the early 1990's, A Tutorial with Signal Names and Definitions, Written by Christopher E. Strangio. In the early 1960s, a standards committee, today known as the Electronic Industries Association, developed a common interface standard for data communications equipment ( DCE ). At that time, data communications was thought to mean digital data exchange between a centrally located mainframe computer and a remote computer terminal, or possibly between two terminals without a computer involved. These devices were linked by telephone voice lines, and consequently required a modem at each end for signal translation. It was thought that a standard was needed first to ensure reliable communication, and second to enable the interconnection of equipment produced by different manufacturers, thereby fostering the benefits of mass production and competition. From these ideas, the RS232 standard was born. It specified signal voltages, signal timing, signal function, a protocol for information exchange, and mechanical connectors.
