Hi,

Would it make sense to have Ctrl-Z suspend the SSH process, or is there some rationale for not doing that? I'm not intimately familiar with how SSH interacts with terminals on pseudo-TTY allocation, which is why I'm asking.
If you force PTY allocation ("-t"), all that stuff needs to go to the
other end. How can ssh know that you want to suspend the local SSH process,
instead of "whatever you are running in the PTY on the other end"?
