Enabling Touch Reporting
First confirm touch reporting is enabled by pressing "P" for the "Touch Reporting"
menu, then moving the highlighting to "Touch Reporting" and press [Enter] so
"Report" is indicated. (Only serial controllers power-on enabled).
Skip to Touch Testing by pressing "T". Touch the touchscreen. X and Y
coordinates will be displayed for the position of your touch, as well as a constant
Z-axis value, transmitted for compatibility with Elo IntelliTouch touchscreens,
which sense pressure as well as location.

The Touch Flag indicates whether a touch coordinate is for the point of Initial
touch, the point of release (Untouch), or points between those events (Stream).
Changing the Touch Mode
The SmartSet controller can be configured so it reports any combination of these
types of events. Press [ESC] to exit the Touch Testing screen, and "M" to enter
the Touch Mode submenu. Use the arrow keys and [Enter] to enable various
combinations of "Initial Touches", "Stream Touches", and "Untouches". Type "T"
to return to the Touch Testing screen to examine their effects.
Return the controller to the "Enabled" setting for "Initial Touches", "Stream
Touches", and "Untouches".
Calibration
The need for calibration is unique to the touchscreen. Unlike mouse or keyboard
applications where the cursor is part of the image, a touchscreen is a physical
overlay with an independent coordinate system. Only by knowing the position of
the image can the touchscreen coordinates be converted into image coordinates.
