Use the baud rate setting to specify the baud rate for the COM port
through which the touchscreen driver communicates with the
touchscreen controller and touchscreen.
Note:
The touchscreen controller must be set to use the same baud
rate as the COM port. If the baud rates are different, the touchscreen
driver and the touchscreen controller cannot communicate. To change
the baud rate for the controller, use Microcal. The default baud rate
for all MicroTouch controllers is 9600.
For more information about using Microcal, refer to Chapter 4.
