Hi,
I'm trying to use connect to an openssh server, setting some terminal
modes, and they don't seem to do what I want. Specifically, I'm trying
to
disable echo from the server - hence the four modes in the sshd trace below
(53 for example is ECHO).
I've looked at the code. 0 would indicate that the option is negated in
the c_lflag field. And it seems like the modes are applied to the pty
successfully (else one would get an error: Setting tty modes failed: ) ...
Yet I still get input echoed on the session. Any ideas? Are these modes not
doing what I would expect them to do?
