The following method is a good method of receiving a rednet message without using rednet.receive(). It is usually used in IRC, Chat programs e.t.c. When a message arrives to a computer, a "rednet_message" event occurs.

The Code

This is a typical Listener which prints the content and the sender id of any incoming message. 

rednet.open("Direction_of_modem")
while true do
  event, id, text = os.pullEvent()
  if event == "rednet_message" then
    print(id .. "> " .. text)
  end
end
