Information and interruption issues

There are two problems with RDM: 1. It will get stuck for a few seconds while copying in ssh (when the mouse is swiped over the relevant characters). 2. When the network is bad, enter in the interrupted ssh window. After a few seconds, the relevant ssh window will close directly and disappear. The previous operating history also disappeared. The ssh window should exist after the network is interrupted, only prompting the network to be interrupted. This way I can still see what I have operated, especially when I come back many days later.
