 Function rednet.send | |
| Allows a computer / turtle with an attached modem to send a message intended for a system with a specific ID. At least one such modem must first be "opened" with eg rednet.open() before sending is possible. Assuming the target was in range and also had a correctly opened modem, it can then use rednet.receive() to collect the message. See also rednet.broadcast(). Note that any systems in range are capable of receiving the message if their owners have some idea what ID you're targeting - they need only use modem.open() To get the ID of a given system, refer to os.computerID(). | |
| Syntax | rednet.send(number receiverID, string message) |
| Returns | boolean success code. True if a message has been sent (note - "sent", as opposed to "received" or even "was receivable"), false if not. |
| Part of | ComputerCraft |
| API | rednet |
