If it is for the aircraft flight control system, and you do not write
in that buffer, then maybe you should designate specific character
position, and you should maybe have buffer empty, with characters
 inside, as to delete character and insert one:

(defun my-char-at-place (position char buffer)
  (set-buffer buffer)
  (goto-char position)
  (delete-char 1)
  (insert char))
TXX   
(my-char-at-place 886 "X" (current-buffer))
(my-char-at-place 886 "T" (current-buffer))
(my-char-at-place 887 "X" (current-buffer))
(my-char-at-place 888 "X" (current-buffer))
