(Question) Rednet receive forever or until keypress

Trying to get a computer to listen for a rednet signal indefinitely until a key is pressed or input is entered.

the code:

rednet.open(side)
while true do
id, dest = rednet.receive()
if input == "x" then
  break -- will stop the while loop
end
end

Doesn't allow me to break the program…

Also, will using

rs.setBundledOutput(side, color, true)
os.startTimer(1)

cut off the output?

The best way to do this is with events, I would check out the tutorial on os.pullEvent for more details but here is a small example of what you will want to do.

while true do
local event, param1, param2 = os.pullEvent()
if event == "rednet_message" then
--do stuff for the rednet message"
elseif event == "key" then -- will detect any key being pressed and return the key number for example the esc key is 1
if "param1" ~= 1 then -- if anything except esc was pressed
-- do key stuff
end
elseif event == "char" then -- will return which key was pressed
if param1 == "x" then
--do different key stuff
end
end
end

Thank you for the quick reply….

This should help me out no end.
