ControlASCII 20 | Hex 0x14 | U+0014
DC4 (code 20) was designated for device-specific control but never received a universal assignment. Some legacy printer protocols used it to deactivate a device or reset operating modes. Like DC2, its meaning varies by implementation. The four Device Control characters (DC1 through DC4) were intentionally left flexible in the 1963 ASCII standard so that equipment manufacturers could assign device-specific functions without conflicting with the standard's fixed control characters.
