(Running version 18.51.1 of  GNU Emacs.)

[NB.  I think I am reporting a possible defect in Suntools, not a bug in Emacs.]


I use  Suntools  on a Sun terminal and envoke Emacs in a Shelltool window by
putting

  shelltool  -Wp  460   0 -Ws 692 891 -WP  256   0  emacs -funcall rmail

in my .suntools file.  My .login calls the  suntools  command.

If, when in Emacs, I accidentally hit C-z (bound to suspend-emacs) my cursor
jumps to the minibuffer location of the Shelltool window and the Shelltool
window seems dead (it echos keyboard input, but seems to execute no commands:
 C-q  and  C-]  and  M-x  do nothing other than echo.)
	The only way out that I have found is to kill the window (using the
mouse to pull down the Quit command) and call my shelltool again.  
	At one time I used the Emacstool command and my memory is that it too
fell victim to  C-z


A candidate solution to the problem is to put into the  .emacs  init file

  ; Prevent C-z from suspending Emacs in a shelltool window (it never recovers).
  ; The .login file sets the SUNTOOLSYES environment variable.
  (if (string= "yes" (getenv "SUNTOOLSYES")) (global-unset-key ""))

which is what I have done.  Is this an appropriate solution?
