Symbol Meaning

The Device Control Two symbol was used mostly in computer terminals, printers, word processing systems, and telecommunication equipment in order to control functions of various devices.

It is one of the four device control characters: DC1, DC2, DC3, DC4. They all provided the ability to transmit special instructions for controlling device functions and modes of operation. The assignment and interpretation of device control symbols depended on the specific device and communication protocol.
