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 meters away, or 16 meters during a thunderstorm. As of 1.4 Modem range is increased with higher altitudes. If there is no thunderstorm, the range will always be higher than 64, and at max altitude you would have a range of 384 meters.

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.
