just by press an area of the screen defined by a box. You can also draw graphics of any kind onto the
screen and place a hot spot around it with touchzone.

P
ressing the touchzone will send TZP1 to the Command Port and releasing it will send TZR1 to the
Command Port. Moving off the touchzone before releasing will generate TZC1.
The touchzone command contains six different values.

touchzones but they should not over lap.

upper left corner.
The [width] and [height] values designate the width and height of the touchzone in pixels.
The [options] designates the state of the touchzone, whether it is pressed, disabled, and et al.
Option choices: 1=enable, 2=disabled .
