[ESS] R in telnet session in emacs: too much ee eecc eecchh ...

[Woodrow Setzer]

I could not get anything to work with telnet, but with rlogin (my preference, anyway), stty -echo echonl works.  Without echonl, a command's output would overwrite the command.  I could not get the function "rmh-comint-toggle-echo" to work at all.  It seemed to just drop newlines.

It is most likely that you need something like
  stty -echo
on the remote side before starting R.
There are a few other stty parameters that might also be relevant.


But it might be something on the local side.
I use the following function

(defun rmh-comint-toggle-echo (&optional arg)
  "Toggle comint-process-echoes.
With arg, turn comint-process-echoes on if arg is positive, off otherwise."
  (interactive "P")
  (setq comint-process-echoes
	(if (null arg) (not comint-process-echoes)
	  (> (prefix-numeric-value arg) 0))))
(define-key comint-mode-map "\C-c\C-k" 'rmh-comint-toggle-echo)

And then I do C-c C-k when the type of echoing you describe happens.


Please report back to this list when you figure out which of these
potential solutions is the one that works.
