Connecting an External Mouse
If you want to connect an external mouse (serial mouse) and use it instead
of the built-in trackball, proceed as follows:
1. Shut down and switch off the device.
2. Connect the external mouse to the COM1 interface.
3. Switch on the device.
The system restarts.
PC-3 board only: During this restart you can switch off the trackball,
proceed as described in the section Switching the Trackball Off or ON.
NOTE. Do not change the mouse driver via the Control Panel applet. This
could make the keyboard unusable.
