Grid Redstone.png  Function rednet.broadcast
rednet.send()s a message on channel 65535. Any modem in range readied for rednet use will be able to receive it.

ComputerCraft 1.6 introduces optional "protocols" - simple string names indicating what the message is about. Receiving systems may filter messages according to their protocols, thereby automatically ignoring incoming messages which don't specify an identical string. It's also possible to lookup which systems in the area are interested in certain protocols, hence making it easier to determine where given messages should be sent in the first place.
Syntax rednet.broadcast(string message, [string protocol])
Returns None
