The question came up when one of my friends impressed us all by getting an almost-decent "Happy Birthday" using the telephone keypad as a piano. I suppose I could always whip out a 'scope and mesuare the tones like we used to do in Physics, but somehow posting seems a bit easier. Thanx, Danny Padwa Padwa@Husc3.Harvard.Edu [Moderator's Note: Yo're excused this time. Yes, this comes up frequently, and there is a file in the archives someplace which gives the references, but perhaps a couple of readers will dash off a note to you.
