in any shell that supports job control

for example for running interactive or gui programs on the console:

see framebuffer-fbpdf function
https://logand.com/sw/emacs-framebuffer/file/emacs-framebuffer.el.html#l654

see framebuffer-fbmpv function
https://logand.com/sw/emacs-framebuffer/file/emacs-framebuffer.el.html#l667

or changing console font:

(defun console-font (x)
  (interactive "sfont: ")
  (suspend-emacs (format "setfont %s;fg" x))
  (message (format "font is %s" x)))
