DE-9 connector

From Wikipedia, the free encyclopedia

The DE-9 (9 pin D-shell connector) is a type of D-subminiature electrical connector most commonly used for the RS 232 serial port on the IBM AT and compatible computers. DB-9 is a common misnomer for the DE-9. (A true DB-9 connector would have 9 pins in a connector the shape and size of a DB-25, the other 16 pins would just be missing.)
