Security Door Program

Just showing a program I made to use the new Protocol system.

This works in three parts: A Master Control Computer, DoorLock computers, and a PDA for remote control.

MCC Code:

rednet.open("top")
rednet.host("Security", "MCC")
while true do
local ID, command, protocol = rednet.receive()
if protocol == "Security" then
  if command == "Back Open" then
    rednet.send(11, "Open", "Security")
    rednet.send(ID, "Clear.")
  elseif command == "Front Open" then
    rednet.send(13, "Open", "Security")
    rednet.send(14, "Open", "Security")
    rednet.send(ID, "Clear.")
  elseif command == "Lockdown" then
    rednet.send(11, "Lock", "Security")
    rednet.send(13, "Lock", "Security")
    rednet.send(14, "Lock", "Security")
    rednet.send(ID, "Lockdown in effect.")
  else
    sleep(0.5)
    rednet.send(ID, "Invalid Command.")
    end
else
  sleep(0.5)
  rednet.send(ID, "Invalid Code.")
end
end

DoorLock Code (Used in three different computers but each is just a clone of the original with new ID)

rednet.open("back")
rednet.host("Security", "BackDoor")
while true do
  local ID, command, protocol = rednet.receive()
  if ID == 12 and protocol == "Security" then
    if command == "Open" then
	  rs.setOutput("top", false)
    elseif command == "Lock" then
	  rs.setOutput("top", true)
    end
  else
    rednet.send(ID, "Incorrect ID or Code")
  end
end 

PDA code:

rednet.open("back")
print("Input Command:")
local command = read()
print("Input code:")
local security = read("*")
rednet.send(12, command, security)
local ID,ReturnVal = rednet.receive()
print(ReturnVal)
sleep(1)
term.clear()
term.setCursorPos(1,1)

Just set the first two on startup and the third as whatever program name you want.
