Perhaps by sending SIGSTOP and SIGCONT, much like hitting Ctrl+Z on the console and later running bg <pid> or fg <pid>.
Note that this is not the same as Ctrl+S & Ctrl+Q on the console – that just pauses the output display not the process (though the process may subsequently pause if a buffer somewhere down the pipeline becomes full due to the terminal output pausing).
