A quit hack would be something like this:

(defun slime-raw-insert ()
  (interactive)
  (let ((char last-command-char))
    (goto-char slime-repl-input-end-mark)
    (insert char)
    (slime-repl-send-input nil)))

(dolist (key (where-is-internal 'self-insert-command slime-repl-read-mode-map))
  (define-key slime-repl-read-mode-map key 'slime-raw-insert))

but then you can't no longer edit the input.  Properly emulating a
terminal with raw mode would be quite a bit more work.


I think, that on SBCL/MacOS it should work if you start SBCL in the
terminal, load and start the Swank server from there, and connect to
it from Emacs with `M-x slime-connect'.  SB-SYS:*TTY* should then hold
the stream to the terminal in raw mode.  This way you still need to
switch windows, but at least you get proper terminal emulation.
