Defines the function of the axis LED on the IK 220.
Prototype: BOOL IK220Led (USHORT Axis,
USHORT Mode);
Axis: Number of the axis (0 to 15)
Mode: 0 = LED does not light up

Reports the status of the IK 220 inputs.
Prototype: BOOL IK220GetPort (USHORT Axis,
USHORT* pPortInfo, USHORT* pRising,
USHORT* pFalling);
Axis: Number of the axis (0 to 15)
pPortInfo: Pointer to a variable in which the current status of
the inputs is saved.
pRising: Pointer to a variable showing whether “set edges”
occurred since the last output.
