[CC+RedPower] Detecting signal from bundled cable

So I'm working on a door that gets opened by the computer and closed when the computer receives input from a bundled cable that's hooked up to a button.
How can I detect when I'm receiving a signal from a bundled cable?

Thanks

Just type help redpower and then you can see how to detect the inputs

Use rs.getBundledInput(side) to detect if there is a redpower signal, it will return a number (which is the color, you can find the number in the mods/ComputerCraft/lua/rom/apis/colors)

Use this to wait for signal:
os.pullEvent('redstone')
If rs.getBundledInput(side) == color then
…
End
