Just changing the registry keys will not immediately change the key
mappings. To notify the keypad driver that the registry has been updated,
signal the "ITC_KEYBOARD_CHANGE" named event using the
CreateEvent() API.
It is also possible to map multiple key presses to one button and to map
named system events to a button. The multiple key press option could be
useful to cut down on the number of keys needed to press in a given situa-
tion or to remap which key behaves like the action key. Mapping events to
a button could be useful to change which buttons will fire the scanner,
control volume, and allow for suspending and resuming the device. If you
need help performing one of these advanced topics please contact Intermec
Technical Support.
At the lowest driver level, the 740 Keypad identifies keys as scan codes.
These scan codes are sent via the keypad microcontroller, and cannot be
changed without modifying the keypad firmware.
