Asynchronous communications: RS-232
- 86 Downloads
In 1962 the Electronics Industries Association (EIA) introduced the RS-232C standard to define the interface between Data Terminal Equipment (DTE) and Data Circuit-termination Equipment (DCE). Since then the growing use of PCs has ensured that RS-232C became an industry standard for all low-cost serial interfaces between the DTE (the computer) and the peripheral. Typical implementations include serial mouse, printers, plotters, accessing remote instrumentation, scanners, digitizers and modems. In 1978 the EIA updated the original standard with a new one called RS-232D.
