Well, I'm really after a few devices:

* Sierra Wireless USB 598 (Sprint/Telus branded)
* Sierra Wireless MC5728V (Feeney Wireless Skyus 3G)

The 598 has VID 0025.  I think the Skyus 3G does, too (at least in some
configurations), but I don't have one in front of me to check.  In any case it
is a very similar part to the 598.  All I have to test with right now is a Telus
demo device (with no service :/) as my other parts were returned to their
respective owners some time ago.

I couldn't get qmicli to do anything with any of the ports, but test-qcdm (from
the ModemManager source tree) seems to like talking to the last port.

These parts definitely have CnS ports.  We've used CnS for an unrelated project
with all of these devices.

In all, I think the ports are as follows:

1. AT commands
2. CnS
3. NMEA 0183 (GPS)
4. QCDM

WRT #3, I remember seeing what looked like NMEA a while back using a Sprint
part.  WRT #4 I've only ever tested the Telus part.

What do you think?

Thanks,
Forest
