Analog Telephone Adapter driver/configuration

I'm looking to use the for . The HandyTone 286 Analog Telephone Adapter is configured with a web browser? Their webpage states that:

Remote Configuration TFTP/HTTP

which makes me think that ATA will work auto-magically, to the extent that no drivers are required. I would configure my linux box with gizmo, plug the phone into the ATA and the ATA into the linux, and then...

I could boot into win2k if necessary.

thanks,
