SEND : sends a message; receiving cubes that don't match id ignore it SENDCMD : sends a command; receiving cubes that don't match id ignore it ACK : acknowledges receipt of a message (only for SEND/SENDCMD messages) BDCAST : broadcasts a message on all faces BDCASTCMD : broadcasts a command on all faces (command will be executed by all cubes that receive it)
is formed by appending an integer count to the end of the sender's MAC address. Example: C6:EA:B8:01:3D:EE+12. The MAC addresses are hashed on each cube.
Note that in implementation, words are semicolon separated as commands can contain spaces.
