The recipe for a modem.

Description

Modems are blocks which can be used to wirelessly transfer data between consoles and turtles, using "rednet" commands. To place a modem on a side of your console, click on the console with the right mouse button while sneaking (with standard settings: holding the left shift button).

It is also possible to turn the modem on and off by typing "rednet.open ( side )" to open and "rednet.close ( side )" to close.

Modems can send messages to other modems located up to 64 metres away, or 17 metres during a thunderstorm.[1]

Example

  • Place 2 consoles and add modems to them by clicking the right mouse button while sneaking.
  • Access them, and start Lua.
  • Once Lua has started, type "rednet.open (<relative location to modem, e.g. left, right>)" on both consoles.
  • Check if there exists a connection: a dim, red light should be found on the modem.
  • Type on one console "rednet.receive (60)". This will make the console freeze for 60 seconds, or until it has received a signal from the other console.
  • Now, type "rednet.broadcast ('<your message>')" on the other console. This should send your message to all consoles connected.
  • Opening the first console should show the message written on the second console.
