Description
Modems are blocks which can be used to wirelessly transfer data between computers and turtles, using "rednet" commands. To place a modem on a side of your computer, click on the computer 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.
In 1.4 and 1.41 there is a miscalculation that causes the range to only be 381 meters at max altitude.
Recipe
Example
- Place 2 computers 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 computers.
- Check if there exists a connection: a dim, red light should be found on the modem.
- Type on one computer "rednet.receive (60)". This will make the computer freeze for 60 seconds, or until it has received a signal from the other computers.
- Now, type "rednet.broadcast ('<your message>')" on the other computer. This should send your message to all computers connected.
- Opening the first computer should show the message written on the second computer.
