Pass the device's hardware IDs through modem creation and use them
when calculating the device's identifier. Add a bunch of testcases
for real hardware to ensure we don't break the device ID in the
future unless we really want to.
And possibly the X225 as well. Can't tell much about the modem and
what commands it supports other than AT+SYSSEL for mode selection.
The driver software and connection manager for Windows/Mac OS X are
written by JRD Communication in China, which is a subsidiary of
TCT, which makes Alcatel-branded phones and data sticks. But it
doesn't appear to be the same firmware as other Alcatel/T&A modems
like X060S and such which are supported by the Longcheer plugin.
