Recommended Standard 232 (RS-232)

The standard for serial transmission between a DTE (computer) and a DCE (modem, mouse, etc.). This is a single-ended (unbalanced) hardware configuration that employs a method of communicating digital information in which the data bits are transmitted sequentially over one line. The typical transmission speed of an RS-232 connection is 9600 bps over a maximum distance of 50ft (15m).
