control code
One or more characters used as a command to control a device or a communications session. Control codes may travel in a separate channel, typically in telecommunications systems, or ride with the data such as the return code that signals the end of a paragraph in a text document. There are countless codes used to control electronic devices. See escape code, return code, control channel and null. |
