Yes. See the Tramp manual for this

(info "(tramp) Remote shell setup")

You could adapt the example like this:

--8<---------------cut here---------------start------------->8---
(defconst my-tramp-prompt-regexp
  (concat (regexp-quote "Host:") "\\s-*")
  "Regular _expression_ matching my login prompt question.")

(defun my-tramp-action (proc vec)
  "Enter the host name in order to give a correct answer."
  (save-window-excursion
    (with-current-buffer (tramp-get-connection-buffer vec)
      (tramp-message vec 6 "\n%s" (buffer-string))
      (tramp-send-string vec "hostname")))) ;; Use the real host name
                                            ;; instead of "hostname".

(eval-after-load "tramp-sh"
  (add-to-list 'tramp-actions-before-shell
               '(my-tramp-prompt-regexp my-tramp-action)))
--8<---------------cut here---------------end--------------->8---

I get this error:

Symbol's value as variable is void: tramp-actions-before-shell

Reminder: I have emacs 24.3.1 (i386-mingw) 2013-03-17, with tramp builin (so whatever version is that).

I now have both 

(require 'tramp)

(require 'tramp-sh)

The previous error is gone, but now the errror is:

Invalid function: (my-tramp-prompt-regexp my-tramp-action)
