EQUIREMENTS
The CLIO keyboard is a custom 63-key U.S. English keyboard, which must meet the
following requirements. Please refer to the document ‘
Jupiter Hardware Overview’
for further
guidelines:
Chording keys ([SHIFT], [CTRL], [ALT], etc..) may be held down while simultaneously
pressing any other key on the keyboard.
The Windows CE shell and applications depend on [CTRL], [SHIFT], and [ALT] being
able to chord with any key on the keyboard.
The keyboard must support optional key repeat. The user may turn auto-repeat on and
off via software control.
The keyboard must support separate key-down and key-up events.
The keyboard should support audio feedback on key down events.
Minimum of 2-key rollover for all keys must be supported.
Chording keys must always support a minimum of 3-key rollover in order to support
double-chording, such as [CTRL] + [SHIFT] + [character].
The keyboard must not preclude Microsoft Windows 95 sticky-keys functionality.
In order to use the
key, Vadem must provide Microsoft with a signed copy of the
Microsoft Windows Logo Key License Agreement. For pre-Jupiter CLIO shipments, this
key may be assigned to be the FN key.
