Data Communications Equipment (DCE)

One of two types of hardware connected by an RS-232-C serial connection, the other being a Data Terminal Equipment (DTE) device. A DCE is an intermediary device that often transforms input from a DTE before sending it to a recipient. A modem, for example, is a DCE that modulates data from a microcomputer (DTE) and sends it along a telephone connection.
