Looks like they are one and same: Per Wikipedia:

RS-232
In telecommunications, RS-232 (Recommended Standard 232) is a standard for serial binary data signals connecting between a DTE (Data terminal equipment) and a DCE (Data Circuit-terminating Equipment). It is commonly used in computer serial ports. A similar ITU-T standard is V.24.

The Electronic Industries Alliance (EIA) standard RS-232-C as of 1969 defines:

* Electrical signal characteristics such as voltage levels, signaling rate, timing and slew-rate of signals, voltage withstand level, short-circuit behavior, and maximum load capacitance.
* Interface mechanical characteristics, pluggable connectors and pin identification.
* Functions of each circuit in the interface connector.
* Standard subsets of interface circuits for selected telecom applications.
