Chapter 2 - About VT/ANSI Programming User-Defined Keys (DECUDK) Note: The DECUDK command is ignored in VT100 mode. The computer has 20 user-defined keys (UDKs). You can define the codes of the keys F6 through F14, F15 (Help), F16 (Do), and F17 through F20. Use UDKs to store and recall text and commands that you often use with applications. You should refer to your application software manual for the commands you can store in user-defined keys. If you use dual sessions, you can define UDKs for each session. However, you can only save one set of UDK definitions. For each session you can use a total of 256 characters to define UDKs. Using UDKs To enter definitions for the 15 UDKs, you program the definitions with DECUDK device control strings. To use a UDK after you have defined it, the computer must be in caps lock mode. For example, if you defined F6, you can use it by pressing the caps lock key for the computer and then the key sequence for F6. Note: The host system can also define function keys. UDK Memory Space There are 256 bytes of memory space available for the 15 UDKs. Space is supplied on a first-come, first-serve basis. When the 256 bytes are full you cannot define any more keys until you clear some of the memory space. Three ways that you can clear space are: • Redefine one or more UDKs by using a DECUDK control string. • Clear one or more UDKs by using a DECUDK control string. • Clear all UDKs with a computer power-up or hard computer reset (RIS) operation. Note: All UDK key definitions are lost when power is lost. Programming UDKs Use the following Device Control String (DCS) format to load UDK definitions from the host.
