Yes. And it is ATD123; not ATD.

Well, did not try that, but they should just be displayed in the
serial terminal.

Anyway, "good" solution is to get ofonod running, then use ofone from
here: https://github.com/pavelmachek/unicsy_demo

But parsing AT commands is easy enough that I can probably hack it
together in few days if neccessary.

That sounds like hard way to do it. There's source available, I'm now
trying to understand it / fit it into Sebastian's driver.
