Enumerating BACnet devices

BACnet devices are very common for interconnecting and controlling HVAC, power and ventilation systems, and many other components in building automation systems. It is possible to gather information from them, such as vendor, device name, serial number, description, location, and even the firmware version with some help from the Nmap Scripting Engine.
