pretty much, yeah (standard single line household)

Whoa... then to make the power supply for the TI all you have to do is:
3 wires from calc
3 wires in recepticle
ground to ground, black to red and white to white, right?
(kids... don't try that at home, adults, same deal)

hmm... I kinda figured that out...

All to often, being "easy" is a big clue that you are doing something
wrong.

Touch tone phones use DTMF (dual tone, multiple freq?) so you'd have to
make a
few tones... and heck... if you are doing that... make a red box (do
those things still work?)

hmmm... too early for April 1st... oh well

Yeah... 9600 modems are cheap (would you use one on your computer by
choice?),
they hook right up (with a pin number or gender changer at most) to the
rather handy, and relitivly inexpensive (~$35 at Staples) Graphlink
cable.
> If it's eaiser than how do you slap 9/25 pins into 3
Suprisingly... out of a serial cable, you can get by with as little as 4
(probably 2 will work, but anyway) wires in a serial connection. But
going from 9 to 3 isn't that hard, processing the data in a PIC (which I
believe is what the Graphlink has) is completely possible.
> you do that and try to process all that and the 9600 would be slower.
huh? 9600 is 9600, unless of course you are still doing that put 2 and
2 together thing... (where it was 2 and 3)

What the hell are you talking about?

Normal modems don't work all that well with cell phones, you could
probably do and analog coupler... but most cell phones are too small...
not to mention that the best places to camp are WELL out of the range of
cell towers. I think I am taking you a little to litterally... oh well.

Your sentence/paragraph structure is a real bitch to try to
read/understand (I'm not saying mine isn't)
