Nope, it really doesn't.  Well besides maybe an easy integration point
with GAtChat library.

Nope, there isn't anything like that.  We have plans to implement
something similar, but in the end most of our modems can be easily
detected via udev, or are on platforms with a well known configuration
(e.g. the Freerunner, etc).  So the motivation to do so is not high
right now.  If you manage to make this work nicely (either with oFono or
something else) we'd love to hear about it.
