It appears to be limited to 14.4k due to patent issues and handles faxes only, but its existence suggests writing a software-only data modem should be possible.
That's exactly what WinModems were, back in the day. The board was nothing more than a DAA, a codec, and an ASIC to transmit and receive the raw data. For V.34, the software required about 60 MHz of clock; for V.32 bis the load was closer to 24 MHz.
