            Bug ID: 3929
           Summary: Reset tty after disconnect
           Product: Portable OpenSSH
           Version: 10.2p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: ssh
          Assignee: unassigned-bugs at mindrot.org
          Reporter: mail at joachim-breitner.de

When using fancy TUI tool over ssh, they often re-configure the
terminal, e.g. enabling mouse support, or turning echo off. If such a
connection gets disconnected ungraceful, the terminal stays configured
as such (e.g. moving the mouse now floods the terminal with junk).

It would be desirable in these situations if ssh would, before exiting,
reset the terminal to the state it was before (like the `reset` tool,
or better like `stty sane` which does not clear the terminal).
