The touchscreen is connected to COM4. Its function is similar to that of a
mouse. The only difference is that you put your fingertip on the screen to
move the cursor.
You will need to install the touchscreen driver before it will work. The
touchscreen drivers for various operating systems are stored on the
CD-ROM disc inside the accessory box. The touchscreen manual can also
be found on this disc. Read Chapter 10 of this manual carefully before you
install the driver.
