    var    io      = (IPacketIOService)service;    // CotpServer uses IPacketIOService.
    var    args    = (PacketChangedEventArgs)e;    // IPacketIOService posts PacketChangedEventArgs when it raises a DataChanged event.
    var    message = args.GetData();               // Read from the packet.
