Chapter 2 - About VT/ANSI Programming menus. If a key is locked and an application tries to redefine the key with a DECUDK sequence, the computer ignores the sequence. • Lock the keys to prevent redefinition. You can lock the keys through the computer firmware menus or from the host (with a DECUDK sequence). New key definitions are unlocked by default. The vertical bar (|, 7C hexadecimal) or pipe character is the final character. It identifies this control string as a DECUDK. Ky1/St1;0Kyn/Stn are the key definition strings. You include these strings between the final character (|) and the string terminator (ST). Each string consists of a key selector number (Kyn) and a string parameter (Stn), separated by a slash (/, 2F hexadecimal). A semicolon (3B hexadecimal) separates different strings. The key selector number (Kyn) indicates which key you are defining. The next table lists the definable keys and identifying values.

String parameters consist of hex pairs in the following ranges: • 30 through 39 hexadecimal (0 through 9) • 41 through 46 hexadecimal (A through F) • 61 through 66 hexadecimal (a through f) When you combine these hexadecimal values they represent an 8-bit quantity. This method lets you use any of the 256 character codes in the key string. You can enter key definition strings in any order. The default for Stn is "empty." The key is undefined. ST is the string terminator. ST (9C hexadecimal) is a C1 8-bit character. You can use ESC (1B and 5C hexadecimals) for a 7-bit environment.
