As far as accessing a serial port, you can always use the IOKit for that . There is sample code on Apple web site for that.
Then you'll get a /plain /old /dev device that you can talk to.

Yes - but I'd need to change some code so I was lazy and didn't port the thing to Carbon ;-)

If you look at the audio drivers you'll see that there is a method called "setModemSound" that is made available to other kernel extensions through a publishresource call. So you need to write a very very small kernel extension with a user client that
will activate that or not. Sample for how to use this call can be found ...in the modem/serial driver source code!

Great - I'll check it out. But will this let me get the audio from any modem-equipped Mac? I supposed that it was impossible to get it, say, on an iBook. Can you confirm or deny this?

Or will this simply let me do what I can currently do under Mac OS 9 by selecting "Internal modem" as the input source for the built-in input device?

Ciao,
Alberto.
