Hi there! Sorry, but "test 2" isn’t a valid command. Figure 5 mainly shows serial port setup parameters—"test 2" is extra info we’ll remove in future document updates to avoid confusion. Thanks so much for letting us know!

About your question: The board automatically prints HDMI data every second. We just want to make sure we understand your needs clearly—could you share what specific info you’re trying to query from the board, or what function/operation you’re looking to achieve?
