Touch_Scanning_On (2AH) (*)

Command Description

The Touch_Scanning_On (2AH) command causes the touch system to

begin scanning the infrared beams. When Report Transfer is also on,

the touch system sends interrupted beam data to the host in the formats

defined by the currently selected reporting method. Both the desired

reporting method and touch mode should be selected before touch

scanning is turned on, although they may also be changed with touch

scanning on. The touch system default setting is touch scanning off.
