Sure -- do this:
[foo@bar]$ emacs
<press control-Z here>
[1]+ Stopped emacs
[foo@bar]$ _
The program that you suspended with Control-Z will remain stopped until you
bring it back into the foreground (fg <jobnumber>), or put it into the
background (bg <jobnumber>). A listing of jobs and their ids that are either
backgrounded or stopped is available by using the jobs command.
Note that this is (AFAIK) bash-only syntax. Job control is a function of the
shell, not the OS.

This, I believe, is not possible to do. Since a program actually is attached
to a /dev/ptyXX or /dev/vc/XX device, the only way it may be possible is if
the program itself has code to do so.
