This page is for the Modem blocks. For the modem API, see Modem (API)

Wired Modem
Item ID	1229
Damage Value	1
Peripheral?	Yes- Modem (API)

Modems are blocks which can be used to transfer data between computers, using the Rednet API or the Modem API. To place a modem on a side of a computer, right-click to place the modem while sneaking. To use the modems, you need to connect the modems to each other by placing cables.

Recipes

Example (Rednet API)

• 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 ring should be found around the modem, closest to the computer/peripheral it is connected to.
• 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 computer(s).
• 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.

Example 2 (Modem and peripheral)

• If you want to use a modem to communicate with a peripheral you might want to take a look at the Peripheral API

Modem as a Peripheral

To use a Modem as a peripheral, you need to either call a method directly using peripheral.call(), or wrap the modem using the Peripheral API. Wrapped modems provide all functions listed in the Rednet API.

For this example, we have a Modem connected to the top of our Computer:

-- Immediately invoke a method without wrapping
peripheral.call("top", "open")

-- You can also "wrap" the peripheral side to a variable:
local modem = peripheral.wrap("top")
modem.open("top")
