Seems to function fine for me as long as you are in the chat lobby. I havent tried it if in a game or in a game chat.
Yes, should show open as long as you you are being connected to bnet server.
In the chat lobby, in the game lobby, in a game also.
Should show close when you logout bnet server.

The only possible if you use game data port, which is not 6112?
