In order to place a modem, right click any side of the computer while holding it in your hand, and holding your set sneak button.

The important Lua codes to control a modem can be seen by typing the following command into the console or turtle:

help rednet

The LUA codes are as follows:

For specifying side of networking

rednet.open(side)

rednet.close(side)

rednet.isOpen(side)

For sending messages

rednet.announce()

rednet.send( receiverID, message) -- Send to a specific computer

rednet.broadcast( message ) -- Send to all computers

For receiving messages

rednet.receive( timeout ) -- Returns: senderID, message

[Note: You can also handle the "rednet_message" event to receive messages without calling receive(), the arguments are the same as the receive() return values.]
