Trying (failing) to get my modem to work

[Wouter Verhelst]

Hi folks,

I have a new laptop, which comes with a 4G modem. To my dismay, this
thing doesn't have an AT port anymore, so I can't do what I used to do
on the old laptop (i.e., send some AT command magic to /dev/ACM0 and run
dhclient).

After looking around a bit, I found that mbimcli manages to find the
modem and can do a few things. But not much.
