RS-232C is a long-established standard ("C" is the current version) that describes the physical interface and protocol for relatively low-speed serial data communication between computers and related devices. It was defined by an industry trade group, the Electronic Industries Association (EIA), originally for teletypewriter devices.

It usually has a DB25 connector but it can also have a DB9 connector. How about a photo of the connectors you need a lead for?
