Elsa only says "does not work under Linux/Unix.

Some digging around after opening the case revealed that the
modem uses a Conexant 11247 USB chip as described in
http://ebiz4.conexant.com/default.sph/SaServletEngine.class/Web/products/pro
ducts.jsp?Type=Prod&ProdFamId=11&ProdCatId=35&ProdSubCatId=72&PartId=421

The next URL gives more information about this:

It don't know exactly how to interpret the following comment, but it might
look like the modem really does not speak mormal tty protocols, but
something
special and only the driver on the computer emulates the tty interface with
the
AT-commands to the user:

> The chipset contains a DSP (Digital Signal Processor) chip, but Controller
functions are
> enacted within software

I guess, I need to find another modem ... *sigh*

Just for completeness: below is a dmesg of the system and when the modem
is attached to the USB bus:
