You might be pleasantly surprised. The FTDI USB-to-serial chips have a
bit-banging mode that's designed for doing this sort of thing, where you
can tell it to just clock a sequence of bits out to the pins (or read
one in) at a fixed rate. It'd need some software fiddling, of course,
and if you're going to that much effort I'd be tempted just to stick a
microcontroller in the way to give the modem a more convenient serial or
USB interface...
