generate not only a "complete" set of blue, red and black boxes, but
also one end of a UUCP
Phrack magazine published some code to generate (encode) and detect
(decode) DTMF tones: http://www.phrack.org/show.php?p=50&a=13
The code detected "blue box" MF, but didn't generate them (although
its fairly easy to modify it to add that functionality).
Yeah, but that was published in 97, Blueboxes and UUCP were (mostly)
dead by then.
The DSP work was done before that. Analog Devices had an app note that
I cribbed.
