Abstract

Function keys can be reprogrammed by using the "Load Programmable Function key" command from the host and the "Define Function" key from the keyboard. The Function key has the assigned Attention ID(AID) code originally. The "Load Programmable Function key" command is used to redefine the function of the Function key from the host. Until a Function key is reprogrammed, its default AID setting is assumed. The "Define Function" key is used to program a Function key from the keyboard. When the "Define Function" key is pressed, the following information appears in the 25th line of a display screen. (Image Omitted) The cursor is located at column 7. First of all, the operator must enter the Function key number to be reprogrammed.

System for Defining Function Key

Function keys can be reprogrammed by using the "Load Programmable Function key" command from the host and the "Define Function" key from the keyboard. The Function key has the assigned Attention ID(AID) code originally. The "Load Programmable Function key" command is used to redefine the function of the Function key from the host. Until a Function key is reprogrammed, its default AID setting is assumed. The "Define Function" key is used to program a Function key from the keyboard. When the "Define Function" key is pressed, the following information appears in the 25th line of a display screen.

The cursor is located at column 7. First of all, the operator must enter the Function key number to be reprogrammed. As soon as the operator specifies the Function key number and presses the Send key, its associated message that was stored in Non-Volatile Memory (NVM) is displayed from column 12 to 75. In case of the AID format, "AID" is also displayed at columns 78 through 80. The cursor is located at the first character position in the message area. The operator can replace this message with any alphanumeric data and ASCII control codes. The message validation test is not performed until its Function is invoked by the keyboard. After an update of the message, the operator must press the Send key to store a new message in NVM. The cursor moves to the key number area in order to allow the operator to continue the programming...
