Red boxing is simulating the tones produced by public payphones when you 
drop your money in. The tones are beeps of 2200 Hz + 1700 Hz 
Nickle = 1 beep for 66 milliseconds. 
Dime = 2 beeps, each 66 milliseconds with a 66 millisecond pause between 
beeps. 
Quarter = 5 beeps, each 33 milliseconds with a 33 millisecond 
pause between beeps. 

There are two commonly used methods being used by Phreaks to make free calls. 
1. An electronic hand-held device that is made from a pair of Wien-bridge 
oscillators with the timing controlled by 555 timing chips. 
2. A tape recording of the tones produced by a home computer. One of 
the best computers to use would be an Atari ST. It is one of the easier 
computers to use because the red box tones can be produced in basic with only 
about 5 statments.
