;; I'm not sure, but I think somebody asked about running kermit under shell
;; mode a while ago. Anyway, here is some code that I find useful. The result

;; systems will not recognize a ^J as an end-of-line character. So LFD is
;; bound to a new function which acts just like CR usually does in shell-mode,
-;; but a ^M is sent as an end-of-line. Funcions are also provied to swap the

;; There doesn't seem to be an acceptably fast way to do this via emacs-lisp.
