"It Depends". For many of them, yes, that's pretty much all there is.
However Motorola (at least) has a reference design for a "WinModem"
that uses their DSP56303 on the board, which has some nice advantages
outside of the fact that the host really doesn't have to do much when
the modem is operating. I have yet to get my hands on one, however.
I've been casually buying WinModems that advertise a Motorola chipset
in the hopes of eventually getting one of these, just because I've
been doing a fair amount of work with the DSP56303 lately. So far,
I've got two $10 coasters -- Motorola also sells "single chip softmodems"
that just have a codec (the PCI interface chip is listed in their product
selection guide, but attempts to get programming information on them
hasn't gone anywhere yet).
This was a topic on slashdot a while back, and there's a website of
marginal value on the topic -- linmodems.org
