Hello Kurt.



 DW> Now, if you had a contraption that would make the touch tone sounds (my
 DW> uncle had one), you could use a rotary phone by punching the number
 DW> into the contraption, picking up the receiver, putting the contraptions
 DW> speaker next to the receiver mic, and then hit the button that told the
 DW> contraption to send the touch tones.  So long, that is, as your line
 DW> supported touch tone dialing.

 KW>  Change the crystal on the contraption, and suddenly your little 
 KW> dialer box is sending 2600hz tones...    :)

Umm... I seem to remember a gizmo called a RedBox or something like that, that was used to trick pay phones by imitating the sound of various coin denominations being inserted.  But that's been decades ago and I might be thinking of something else, but it was illegal as all get-out.

Best regards,
Marc
