In telecommunications, RS-232 is the traditional name for a series of standards for serial binary single-ended data and control signals connecting between a DTE (Data Terminal Equipment) and a DCE (Data Circuit-terminating Equipment). It is commonly used in computer serial ports. The standard defines the electrical characteristics and timing of signals, the meaning of signals, and the ...physical size and pin out of connectors. The current version of the standard is TIA-232-F Interface Between Data Terminal Equipment and Data Circuit-Terminating Equipment Employing Serial Binary Data Interchange, issued in 1997.

applications of RS232:

>Dial-up modems
>GPS receivers (typically NMEA 0183 at 4,800 bit/s)
>Bar code scanners and other point of sale devices
>LED and LCD text displays
>Satellite phones, low-speed satellite modems and other satellite >based transceiver devices
>Flat-screen (LCD and Plasma) monitors to control screen >functions by external computer, other AV components or remotes
>Test and measuring equipment such as digital multimeters and >weighing systems
>Updating Firmware on various consumer devices.
>Some CNC controllers
>Uninterruptible power supply
>Stenography or Stenotype machines.
>Software debuggers that run on a 2nd computer.
>Industrial field buses
