Do you have any documentation or examples of how userspace uses this
interface?  I'm starting to see a proliferation of methods by which
userspace now has to talk to cellular modems and I'd like to keep a
handle on them, despite the fact that they all pretty much do the same
thing and thus you'd think they'd expose about the same interface...
