5.3.4.9 V_CCPCUR (BP = 008AH)
The V_CCPCUR service converts scancodes from the HP cursor control pad to their respective
numpad or cursor control equivalents. The
<
Shift> key states in the keyboard state variable are
adjusted to cancel the effect of the
<
Num lock> key and force the Numeric keypad to operate
in cursor mode. Upon return from this translator chain, the logical keyboard driver generates the
appropriate
<
Shift> scancodes to account for the change to the keyboard state variable.
F_ISR (AH
=
OOH)
This function translates the scancode to its Numeric keypad equivalent, changes the Data Type to
T_KC_IBM_PC, and adjusts the keyboard state variable to force the Numeric keypad into
cursor mode.
