It provides something that looks just like a typical serial port to the application, but underneath is layered on top of IrLAP (packet based link level prototocol for IrDA). This means (...)

(...) Not really -- the tower uses its own proprietary communcations format. It's similar enough to that used by remote controls that learning remotes can pick up the signals, but I haven't heard of anyone going the other way around.
