Function rednet.receive
Waits for `timeoutSeconds` or until another computer sends a message to this computer. (see rednet.broadcast( message ) and rednet.send( receiverID, message ). If a Timeout occurs the return id and message are set to nil. If timeout is nil, waits forever. To get the id from a computer see os.getComputerID(), or the id command. You must be calling this function at the moment a message is sent, or you will miss it. If you need to watch for messages while doing something else at the same time, see Parallel.waitForAny
