Hi Guys!

I am currently programming a router program for ComputerCraft and i have a wired modem and a wireless modem. How do i only receive messages with the wireless modem and send the received message across the wired modem network.

Thanks!

When you call rednet.send() or rednet.receive(), all open modems are used. So it's simply a case of rednet.open()ing the wired modem and rednet.close()ing the wireless before sending, and vice versa before receiving.

Well if i close off the wired modem and only keep the wireless modem on then how will i be able to upload data because only the download portion will be active if i do that

Is there a way i can make a custom rednet API or something to only use the selected modem side or something

As mentioned, invert the modem states.

rednet.open("yourWirelessModem")
rednet.close("yourWiredModem")
local sender, message, protocal = rednet.receive()

rednet.open("yourWiredModem")
rednet.close("yourWirelessModem")
rednet.send(target, message)

You can also use the native modem API, but rednet already handles the IDs.
