Yes, in theory it is entirely possible to use an FXO card driven by software 
as a modem  (and indeed, this is exactly what Winmodems do);  although you 
will have to do all the hard work of generating the outgoing tones, and 
decoding the incoming tones, yourself.  This is a highly non-trivial task, and 
there is almost certain to be a better way than this of achieving whatever you 
want.
