munication

Responding touch panels tell the sending touch panel to change its Main page to the color
white.

Example:
• 10.4" panel serial port is connected to TPI program port.
• 10.4" panel wants to verify communication between the TPI and itself.
• 10.4" panel issues "WORKING?" to its serial port. It will be sent as ’$SP "WORKING?".
• TPI receives the command and responds to the 10.4" panel by telling it to set the Main
page background to white.
