Hi, first, I am sorry for joining the game so late. I was sick and have had a lot of pending tasks after Christmas's holidays and the sickness.

What is the exact scenario for this feature, please? IMHO, rewinding the entire log on an unresponsive terminal has a questionable value. Most messages would scroll down quickly and only the last messages would stay visible. Also this code would rewind all consoles, including (slow) serial ones. I wonder if rewind on these consoles would be useful as well. That said, I am not completely against this feature. I just want to be sure that it does what you expect. Best Regards, Petr
