Yeah, but maybe he's talking about a change of frequency.  This could be
expressed in baud/s, as in, "When I plug my modem into the 230V socket for my
dryer, the OH light starts blinking at a rate of 300 baud, and after two
seconds the frequency increases by 2400 baud per second until it blows up."

Or maybe not. :)
