Keyboard ID
Provided by the ASK Keyboard Dictionary
A keyboard ID is a value a keyboard might return to a host computer or terminal to identify what it is and possibly what language/region it's intended for. Some keyboards (notably IBM 3270-family terminal and terminal emulator style) may have setup switches on their underside to allow the operator to change some bits that make up its KBDID, and some may even have a header on its controller card that allows some or all of the KBDID to be set with jumpers. For IBM PC-compatible keyboards without setup switches or jumpers, the value is typically fixed. For example, typical IBM PS/2 Enhanced Keyboards should respond with the byte sequence 0xAB 0x83 if the host computer asks the keyboard to identify itself.
