Yeah they are right dialing and getting a response have nothing to dowith databits etc..
basically when war dialing your using your modem as a automated phone. Which just dials numbers in a range or randomly depending on your settings and then if it gets a response from a listening computer it stores this number in the got one list.. Thats how it worked.. and in New Zealand thats how i got access to old networks.. not many people use modems in wans or anything anymore
The wise make mistakes, the fools repeat them
When you have eliminated the impossible, that which remains, however improbable, must be the truth
