Modem/Rednet update help

I think I need some help with the new modem update.
What I am having trouble with is how to send/receive? I have tried this:

Spoiler

computer 1:

  modem.open(1)
  local receiver = {os.pullEvent("modem_message")}
  for k,v in pairs(receiver) do
	print(v)
  end

computer 2:

  modem.open(1)
  modem.transmit(1, 2, "hello world")

What am I doing wrong?
Does computer 1 have to do something else to receive it?
Does computer 2 have to do something else to send it?
Is it both?

And Yes, i started computer 2 after computer 1.

Did you wrap the peripheral first? If not, you need to add this in the code for both computers:

local modem = peripheral.wrap("top")

Replace "top" with whatever side your modems are on.


What problems are you experiencing exactly? It's difficult to help if we don't know what the problem is.

Yes I did wrap it, but it seems to just not send. computer 1 doesn't receive it or computer 2 doesn't send it

Post the full code of both programs. Also, post exactly what shows on both computers, particularly computer 1.
