 ## Socket Commands
 
-Send a simple broadcast
+#### SOCKETTEST
+Message for testing purposes which repeats:
 ```
-BC:<DATA>    
+SOCKETTEST
 ```
-Send an ARQ like frame which will ask the receiver for acknowledgement
+"WELL DONE! YOU ARE ABLE TO COMMUNICATE WITH THE TNC"
+
+
+#### TRANSMIT ARQ MESSAGE 'HELLO!'
 ```
-ACK:<DATA>    
+ARQ:HELLO!
 ```
 
+#### SET NEW CALLSIGN
+```
+SET:MYCALLSIGN:AA1AA

+#### GET CALLSIGN

+#### GET CALLSIGN CRC8
