Appendix C — Remapping the CN2A Keypad
140 CN2A Mobile Computer User’s Manual
The CN2A remappable keypads support two meta keys (the
Orange
key and the Green key) as well as three scan
buttons.
To accomplish this, Intermec extended the Microsoft virtual key
(VK) code convention. Standard VK codes are less than 0x100,
and the new VK codes are greater than 0xff.
These codes can be used when mapping the keypad to assign
these functions to a key or combination of keys.
Key mapping entries are 16-bit (WORD) sized (or multiples
thereof ), and other keypad attributes are 32-bit (DWORD)
sized.
Understanding Keypad Attributes
The keypad attributes are as follows.
• "OrangeObeyClear" = dword:0
