As I said they are MOSTLY obsolete. If you have a specific target you are looking for dial-up access to,thats one thing but the good old days of wardialing an entire exchange are over. And non-sequential war-dialing is not new, it still doesnt stop people from calling back as your modem plows through hundreds of numbers an hour this starts to become a real inconvienence to the would-be wardialer. One of cool ones was called Code Thief Deluxe people used to use that would not only log numbers with carriers but could be used to hack PBX's and calling cards using random #'s or templates and could be configured to do all sorts of stuff. If someone is really interested I might be able find a copy on floppy somewhere but its pretty dated stuff, still....its a neat little piece of hacking history.
