API's for serial port access.
I'd guess that Graeme is quite familiar with them, since argyll
supports serial port devices. :-)


Yes, modem lines can be sampled, although I don't think the software
interface in Argyll is setup this way. It sounds easy enough
to create an interface of some sort, although using software sampling
is always a dodgy proposition on a multi-tasking operating system.

Another option for instance would be to buy something like
this <http://www.ftdichip.com/Products/EvaluationKits/DIPModules.htm>,
and put it in "bit banger" mode to plug it into USB.
