Hi,

i was trying to figure out if there is way to demodulate traffic by tapping a
modem line which is called i think *blind demodulation*. I've looked for
solutions like using a sound card or using the lucent winmodem. I'm not
interested in if the impedance of the line decreases as a result of
interception. I am just looking for theory and maybe some basic application.

Thnx.
