jew.c v1.1 is a linux based bluebox program. Features DTMF dialing, CCITT 5 dialing, some c5 toys, ACTS tone generation, and more. Dosn't studder like ADM's linux tone generation program.

Jewbox v1.1 by Morbie
(jevhova1@dobbs.com)
Note: This is still work in progress.
Current features:
DTMF Dialing
CCITT5 Dialing
Some C5 toys.
ACTS Tone Generation. (Gay, but oh well.)
Pause (Yay!)
!!Fixed Things!!
I made a stupid mistake and made 'hash'(pound) the actual sign, and the
same with star. Ewpz. They were replaced with H and P.
I don't know what I should do in the future with this, aside from giving it
a WAY better interface. If you play with the source any and make any
signifigant improvements, please send them to me.
Have fun, and stay out of trouble.
Compile by using the following commands with cc.
cc -O jew.c
cc -O jew.o -o jewbox -lm
--Morbie
---------------------
Shtuff:
1 through 0 - DTMF
q through p - CCITT5 (Note: Each letter represents the number above it on the
keyboard. So q = 1, w = 2, and so on.)
h == Whatever trunk you program. The default is 2400 x 2600 for 150 MS.
j == 2400 for 150 MS. This is standard.
(And now a gay addition, but someone was bound to do it anyways.)
m == A 'Nickel' in ACTS. 5 'Nickels' in a row makes a perfect Quarter. It's
what I use on my watch, and it works perfect. (Get them at Rat shack.)
n == A pause feature. Length editable via flag.
a == KP1
s == KP2
d == ST
f == Code 11
g == Code 12
---------------------
(gtk interface for creating dial scripts coming soon.)
