I've discussed this with Frank Naumann. It's true, there are HS-Modem IOCTLs
that *can* be used for this. This is done by configuring the device and see
what fails (not supported) and what works (supported). I don't like this
approach much though, you shouldn't have to change any parameters just to
see if you can...
