-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Probably not damaged, you might hear random noise that's all. You actually output from the line out on the debugged machine, to the line-in on the machine used for monitoring (you use a male-male audio cable). On the monitoring machine is the "modem" (implemented in software) that converts the "audio" signal into data (text) - same way a normal modem works (this actually is a real modem).
