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
