These two functions used to work with my ADM-220 clone, when I had one:

(defun 80-columns ()
  (interactive)
  (send-string-to-terminal "\033[?3l")
  (set-screen-width 80))

(defun 132-columns ()
  (interactive)
  (send-string-to-terminal "\033[?3h")
  (set-screen-width 132))

       .                           Regards,
