[hercules-os380] no echo

[[e-mail] [hercules-os380]]

When using vi/emacs on z/OS, is local
echo on the terminal switched off?

It seems to me that when entering
ESC g to go to a particular line number,
you don't want a "g" to be entered
on the screen at the current cursor
position.

So does the application on the host
(z/OS) echo typed characters? If so,
how does the application manage to
switch off echo? What's the API call
to do that?

Thanks. Paul.
