**Cap'n Crunch revisited??** By Captain B

Well, not exactly. And, before I go any further, let me say that this
file was written more for entertainment and nostalgia sake. (Well,
It's nostalgia for those who remember fondly the days when blue boxing
could be done with a mere toy whistle gotten from a box of cereal). As
far as the info content goes, you may not find it particularly useful.
But hopefully, you'll find this "file" to be at least somewhat
interesting. Not too long ago, I decided to try to do my own sort of
"toneing" with a whistle trick. Yeah, yeah, I know you can't do it
anymore with SS7's out of band signalling. But, I didn't care. On a
whim, I bought a pack of Whistle Pops candy from K-mart for the
purpose of trying to send tones via accoustic coupling. (Throught the
handset mouthpiece). Whistle Pops are basically lollipops shaped like
a whistle. I think this candy has been around for some time now, but I
can't recall seeing it sold anywhere but K-  mart. The candy costs 99
cents for a pack of 4. It has a built-in slide whistle. Sliding it out
further produces lower pitched tones, sliding it in produces higher
tones. And, for some reason, it even has the numbers 1-9 marked at
successive points on the slide. And, the numbers go in descending
order when sliding it out. I found that when I slid the slide out to
about 6, it recognized the tone as being the # key. Yeah, I know,
you're probably saying "So #@?$*! what?" Well, I just think It's
somewhat cool and unusual that it's  recognized as being any kind of
DTMF tone. Also, I found that you may be able to get the CO equipment
to think your sending DTMF tones by making certain high pitched tones
into the mouthpiece with nothing more than your own vocal cords. It
can be somewhat difficult to try doing it that way. And, it helps if
you have a fairly good ability to hit some pretty high tones with your
voice. Anyway, all of this obviously pales in comparison to being able
to blue box with a toy whistle. But, I guess It's about the closeset
thing to it nowadays. Written with acknowledgemets and props to Cap'n
Crunch.
