RS-232 is an EIA standard for serial digital communication ("Interface Between Data Terminal Equipment and Data Communication Equipment Employing Serial Binary Data Interchange"), originally issued in 1960.
The 1969 version RS-232C introduced a standard 25-pin D-shell connector (albeit only in an appendix, formally added to the next version RS-232D in 1986).
Related ITU-T standards include V.24 (circuit identification) and V.28 (signal voltage and timing characteristics).
