CTRL-S doesn't suspend the process, that's CTRL-Z - CTRL-S sends an XOFF
flow control symbol (stop!), telling the system (remote end to a terminal)
to stop sending to the terminal. CTRL-Q sends XON (go!), allowing the
process to continue. These control codes are a historical feature that
wasn't for flow control originally - they simply turned the paper tape
punch on and off, but I find them quite useful while viewing fast-changing
logs.
