The communication settings being used by the touchscreen driver
to communicate with the touchscreen controller do not match the
communication settings used by the touchscreen controller.
Use Microcal to determine the touchscreen controller settings.
Use the Hardware Controls dialog box in the Touchscreen Control
program to modify the communication settings used by the
touchscreen driver so that they match those of the controller.
For more information on Microcal, refer to Chapter 4. For more
information on the Touchscreen Control program, refer to

Another device is using the same COM port, IRQ, or base address
as the touchscreen controller. Use Microcal to specify unique
communication settings for the touchscreen controller. Use the
Hardware Controls dialog box in the Touchscreen Control
program to modify the communication settings used by the
touchscreen driver so that they match those of the controller. If
you are using Custom communication settings, be sure that the
base address is correct.
After changing the communication settings, reboot the system.

be sure you touch the center of each target firmly and precisely.
