Using Terminal Emulation Mode
Use Terminal Emulation mode to send firmware commands directly to
the touch controller, and to view touch position data sent from the
controller.
To access Terminal Emulation mode, press F4.
You must enter commands in all uppercase characters. When you
press Enter, Microcal sends the command to the touch controller at
the current baud rate. For a description of the available firmware
commands, refer to the Touch Controllers Reference Guide.
A response may indicate the controller successfully executed the
command, may report the output identity of the controller, or may
display the X, Y coordinate position of your touch on the screen.
