One tells the system to suspend it.  Yes, this does require some sort of
facility for doing so.  No, it does not require mysterious signals with
bizarre semantics, magic control characters, or any of the other sludge
that job control brings along.  You've got other windows, remember -- you
can use one of them to request the suspension, and to fiddle with the
process thereafter.
