The rednet API provides a simple computer networking model over RedPower bundled cables or the Wireless Modems of Computercraft 1.3. With the table below, 'side' refers to a string that represents a side of the computer ("front", "back", "left", "right", "bottom", "top"). All message sent with rednet are and must be strings.
| Method name | Description |
|---|---|
| rednet.open( side ) | Tells the computer that the side can be used for networking. |
| rednet.close( side ) | Tells the computer that the side can no longer be used for networking. |
| rednet.announce() | Broadcasts an empty rednet message. |
| rednet.send( receiverID, message ) | Sends a message to the computer using the opened sides. The receiver ID is the ID (number, not string) of the computer you're sending the message to. |
| rednet.broadcast( message ) | Sends the message to ALL connected and open computers. |
| rednet.receive( timeout ) | Sets an amount of time to wait for a rednet message input. If you wanted to have the computer wait for an input for 5 seconds, then the code would be: rednet.receive( 5 ) |
You can also handle the "rednet_message" event to receive messages without calling receive(), the arguments are the same as the receive() return values.
