Sending instant messages using Control Panel GUI

Question: How does the Control Panel GUI work for instant messages?



The user can enter any ASCII characters under the messaging tab in the Control Panel GUI  and once the user clicks on the “Send” button, the Control Panel GUI breaks up the input string into  different packets with 31 characters each and transmits on the Powerline with custom command ID = 0x33. When the destination node receives a packet with custom command ID = 0x33, it will display the received data as ASCII characters.
