Here's a way in elisp.  Generalization ala read-from-minibuffer is
left as an exercise for the reader.

(defun read-silent (prompt)
  (message prompt)
  (let ((chr (read-char))
	(ans ""))
    (while (not (eq chr ?\r))
      (message prompt)
      (setq ans (concat ans (char-to-string chr)))
      (setq chr (read-char)))
    ans))
