Here is something that was described in one of the read-me files with the
GNU Emacs that redefines ^S as ^\ and ^Q as ^^, so that any place you
are to type ^S you'll type ^\ etc.

;; First make a translate table that does the identity translation.
(set-input-mode nil t)
(setq keyboard-translate-table (make-string 256 0))
(let ((i 0))
 (while (< i 256)
  (aset keyboard-translate-table i i)
  (setq i (1+ i))))
 
;; Translate ^S to ^\ and ^Q to ^^
(aset keyboard-translate-table ?\^S ?\^\\)
(aset keyboard-translate-table ?\^\\ ?\^S)
(aset keyboard-translate-table ?\^Q ?\^^)
(aset keyboard-translate-table ?\^^ ?\^Q)

On the subject of ^S/^Q for flow control, I must say that in this day-and-age
there is no reason for terminals and computers not to use electronic flow
control (CTS/RTS) for async communication.

Hope this helps (not including my opinion)
