I don't think a clear consensus emerged, but the trend was towards
substituting ^\ for ^Q and ^^ for ^S.  This is the convention we are
using at Cornell, and the convention I would like to see other sites
adopt.  It is, I think, the convention RMS describes in the gnu emacs
installation instructions.

The ^\ part is fairly clear.  The problem with ^^ is that it's the escape
character for kermit.  So a possible alternative is to use BOTH ^^ and ^]
as substitutes for ^S.

Note that in gnu emacs the substitution should be done using code such as
the following (from our site-init.el):

  ;; Turn on CBREAK and flow control (wish we didn't have to do this!)
  (set-input-mode nil t)
  ;; Make a translate table that does the identity translation.
  (setq keyboard-translate-table (make-string 128 0))
  (let ((i 0))
    (while (< i 128)
      (aset keyboard-translate-table i i)
      (setq i (1+ i))))
  ;; Now alter translations of some characters.
  (aset keyboard-translate-table ?\^\\ ?\^q)
  (aset keyboard-translate-table ?\^^ ?\^s)
