300 baud.... Ha! That brought back some memories..... none of 'em good.


Same here -- none of them good, but one of them strange... while dialed in to
work late one evening, with the stereo on in the same room, I discovered that
certain notes played on a clarinet produce *exactly* the right tone to cause
