I am not very versed in that kind of programming,

but I managed to write the following code so far:

local modem=component.proxy(component.list("modem")())
local turbine=component.proxy(component.list("br_turbine")())
modem.open(1)
local target = false
while true do
	local e, to, from, _, _, command = computer.pullSignal()
	if e == "modem_message" then
		if command == "s" then
			modem.send(from,1, "Handshake")
			local target = from
		elseif command == "a" then
			if (turbine.getActive()) then
				turbine.setActive(false)
			else
				turbine.setActive(true)
			end
		elseif command == "c" then
			if (turbine.getInductorEngaged()) then
				turbine.setInductorEngaged(false)
			else
				turbine.setInductorEngaged(true)
			end
		elseif (target) then
			local data1 = tostring(turbine.getActive())
			local data2 = tostring(turbine.setInductorEngaged())
			local data3 = tostring(turbine.getRotorSpeed())
			modem.send(target,1, data1, data2, data3)
		end
	end
end

But if I try to run it I only get the error message:

Quote

bad argument #1 (string expected, got nil)

and I haven't a clue what did I wrong where.
