This patch modifies mm_3gpp_parse_iccid() to auto-detect if an ICCID
response is character swapped or not by comparsing the major industry
identifier part of the ICCID response to the known value (89) for
telecommunication purposes. This addresses the issue where the same AT
command (e.g. AT^ICCID used by the huawei plugin) does not report ICCID
in a consistent format.
And also make it a list of masks, specifying which are the specific combinations
supported, not just one mask with all.
E.g.:
-------------------------
Hardware | manufacturer: 'Sierra Wireless, Incorporated'
| model: 'MC7710'
| revision: 'SWI9200X_03.05.19.04ap r5475 carmd-en-10527 2012/09/17 17:57:14'
| supported: 'gsm-umts
| gsm-umts, lte'
| current: 'gsm-umts, lte'
| equipment id: '358178040668164'
The GetNetworkTime() response is defined to be an ISO8601 string, which
is in turn defined to be in local time. Make sure that's reflected in
the documentation, and append the timezone offset to UTC where we have
it.
Oddly, Icera devices return their time info in UTC with an offset to
the local timezone, so we have to jump through some hoops there to
convert the response to localtime based on the reported offset.

Pantech UMW190 modem uses a custom +CMGL response which includes only
three fields before the actual PDU, e.g:
+CMGL: <index>,<status>,<something>\r\n<PDU>
instead of what we had before:
+CMGL: <index>,<status>,<alpha>,<length>\r\n<PDU>
The CMGL parsing logic is now updated to use a regex to match the reply, and
also considering the UMW190 specific case.
Actually, we end up reading only the two first fields (index and status) which
are the ones we really need, so we skip the <length> and the <alpha> if given.
Added also unit tests to cover all these known cases.
Partially fixes https://bugzilla.gnome.org/show_bug.cgi?id=696723 (missing the
actual PDU parsing fixes).
+GSN response differs widely between modems. Some prefix the
MEID and/or ESN with 0x, some have leading zeros, some return the
MEID and the ESN, and some append the serial number to the end of
the IMEI. Handle that and make the ESN, MEID, IMEI, and
EquipmentIdentifier parsing consistent.
This patch adds the support for solicited/unsolicited EPS network
registration status via AT+CEREG, which is configurable via the
'iface-modem-3gpp-eps-network-supported' property of the
MMIfaceModem3gpp interface and is disabled by default.
In QMI modems the logic behind supported and current bands is completely
separated in different services (DMS vs NAS). Actually, the list reported by NAS
as current band preferences seems to include more values than the ones reported
by DMS as supported bands (e.g. CDMA bands are reported even if the firmware
image is GSM/HSPA only).
So, just clean up the list of current preferred bands so that no more than those
given as supported is used.
Some devices, e.g. ZTE MF820D, seem to prefix the `AT+CGMM?' response with the
`+CGMM:' string, resulting in the following model string being loaded:
model: '+CGMM: "MF820D"'
Avoid this by:
1) Removing the expected prefixes.
2) Unquoting the resulting string.

Instead of using a predefined set of string values for 'ip-type' in
Modem.CreateBearer() and Simple.Connect(), we'll use an enumeration. The
implementation will then need to convert the requested IP family type to e.g.
the correct PDP type in 3GPP modems.
This change also consolidates the use of enums in dictionary properties when
possible to do so, as with the Rm Protocol.
We can now return a mask of flags specifying more than one access technology,
and therefore the order is not really important any more, unless for special
cases like looking for substrings of valid expected strings (e.g "HSPA" and
"HSPA+").
Also, add "LTE" in the list of expected strings.
We provide the result of the +COPS=? parsing in a GList of MM3gppNetworkInfo
structures. We avoid the previous hash table, or using a dictionary, as a
list of structs with a predefined set of elements, which should be easier for
plugins wanting to make their own version
The property EnabledFacilityLocks on the .Modem.Gsm.Card interface
is a bit mask that indicates which of the various personalization
codes from 3GPP TS 22.022, plus the SIM PIN lock and SIM PIN2 lock,
are enabled. The set of facility locks supported by the modem is
determined at the time the modem is initialized, and the state of
each supported lock (enabled or disabled) is determined. When the
state of a lock changes, a property-change signal is sent out. Note
that ModemManager only supports enabling and disabling SIM-PIN, via
the EnablePin method on Modem.Gsm.Card.
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.
This is computed before any PIN is entered, and thus before we can
usually get IMEI or MEID/ESN out of the device in many cases. It's
therefore not the same as EquipmentIdentifier.
This is intended to be used by UI programs for matching devices with
PIN numbers for automatic unlocking. While the PIN number is actually
*SIM* specific, no modems allow access to the IMSI before the PIN is
entered, and thus we cannot actually match the PIN with the SIM. The
device ID is the next best thing we can use and should allow auto
unlocking in most cases.
