Re: Wardialing - Odd Results

[Diego Kellner <dkepler () gmail com>]

It might sound silly but when I did my wardialings, most of the
connections that appeared as 300NoEC turned out to be fax machines,
and the only way to check this was by sending a small piece of blank
paper and get the confirmation from the remote fax.
Of course, you'd be fooled by PCs that can both answer as Data or Fax,
but then again... if your wardialing software couldn't figure out the
way to connect to it, and your fax machine did, chances are that it IS
a fax machine after all.
