RS-232 is a simple serial communication standard in which one bit of data is transmitted at a time over a serial cable at the relatively slow rate of up to 20K bits/second and distances up to 50-ft.

It was later adopted by the personal computer industry so PCs could connect to modems, peripherals and data acquisition devices such as lab test equipment, GPS receivers and point of sale terminals. RS-232 (originally called Recommended Standard 232 but shortened to RS232) was developed by the Electronic Industry Association (EIA) in the 1960s for the exchange of data between DTE (Data Terminal Equipment) and DCE (Data Communication Equipment).
