USB interface 0 isn't a serial interface; it's probably a custom
Nokia PhoNet port or a custom Icera pseudo-ethernet port. But
it's not a CDC-ACM serial port, at least on the CS17.

Various bits of the code didn't check if response was valid
or not during error conditions, and when an error occurs
sometimes it'll be NULL (since not all errors are translated
errors from the modem, some are serial or general ones). We
have to make sure we don't try to use response->str when
response doesn't exist.
Found in the generic CDMA code likely as a result of
d5d9eec2b52363a7460aeec0c020b1c6a7af6b03 but was a bug long
before that commit happened anyway.

They appear to always want PPP to happen on interface 0, according
to the Windows .INF files.

Added a PinRetryCounts property on org.freedesktop.ModemManager.Modem.
This is dictionary that records the number of PIN tries remaining
for each of the possible PIN code types for which the modem is
capable of reporting the count. Also, these counts are kept up
to date across ChangePin and EnablePin operations, not just when
an unlock is attempted.

Probably needed in generic USSD code.
|
|
ModemManager currently encodes the USSD command *141*0# (for MTN South
Africa) as "AA182DA6828D00".
While this works on some modems, for example the E1820, other modems,
for example the E160, require USSD commands that are a multiple of 7
characters long to be padded with 0x0d.
Huawei Mobile Partner dashboard software for Windows encodes *141*0#
as "AA182DA6828D1A" which works on both the E1820 and the E160.
The attached patch pads the USSD command with 0x0d before encoding if
it is a multiple of 7 characters long.

In particular, g_regex_match() and g_regex_match_full() allocate a
match_info structure on both success and failure, so calling
g_match_info_free() only in the success case is insufficient.

Passing E1 and E0 afterwards seems to properly disable the echo in Nokia modems
(N900 and C7 at least)

Add the vid/pid for Ericsson H5321gw/w, F5321gw/w, C5621gw/w, C3304w and Dell DW5560.

On a ZTE MF626, sometimes the aux port will respond only with
"ERROR" to probing commands (while the SIM is starting up) and
previously we'd lose the port because we were only looking for
valid probe responses. But if the port returns ERROR or CME ERROR
etc we know it's an AT port and that we can use it once we've
gotten the type response (CDMA or GSM) from the main port.

Need to reset password to NULL after freeing it.
|
|
The F5521gw resets various port properties like echo when the port
is flashed, which was happening on disconnect. Since MM had already
turned of echo with ATE0, and the AT parser in-use expected no
echo, this confused MM when the port magically started echoing commands
back. We don't need flashing on the Ericsson devices because there
will always be a free AT port even if PPP is used for a secondary
PDP context, so we can just skip flashing entirely for these
devices.

During the explicit access technology check, the plugin would request
specific 2G (OCTI) and 3G (OWCTI) technologies explicitly. Some devices
(like Nozomi) don't support the AT_OWCTI command, which leaves us with
only AT_OSSYS for determining whether the device is registered with
the 3G network or the 2G network. So like the unsolicited mode change
handling code, when requesting access technology explicitly, ask for
generic 2G/3G tech first, and then get the specific tech. If the
device doesn't support explicit 3G tech then at least we have the
generic 3G tech from OSSYS to use.
|

The Nozomi cards were early CardBus devices that used a direct PCI
interface (instead of the more usual PCI<->USB controller) and the
'nozomi' kernel driver. They use the same command set as most other
early Option NV modems. Nozomi was always supposed to be driven
by the option plugin, but apparently that got broken when adding
some of the driver/vendor checks.

Huawei wants the USSD as packed GSM.

This reverts commit 1e1bfbf1d808e557441afdae44447af457dae7ff.
Aleksander says this might break RS232<->USB converter connected
Cinterion modems, so we'll need to handle this issue another way.
|
|
Caused a crash with the Sierra plugin due to an assertion failure;
the Cinterion plugin shouldn't claim to possibly support ports
it knows it won't support. In this case, it claimed to support
Sierra modems, so it would try to run probing after Sierra had
done so. Ideally this should work, but for now just make sure
the Cinterion plugin doesn't claim to support these ports when
it knows it doesn't.

See 46d757faa768db7d7bb23d51cc2af3196f7a7e30:
gsm: send init command twice to make the N900 happy (rh #583691) (lp:765516)
for what I think is the real workaround for this bug.

Obviously only works while disconnected since the Gobi devices only
provide one AT-compatible tty.

The Y3400 is functionally nearly identical to the Y3300.

Otherwise, power-up after going to standby will not work properly
|
|
AT+CFUN=4 will be used when available to go to standby mode. If not supported,
(as in EGS5) AT+CFUN=7 will be used instead, which enables a CYCLIC SLEEP mode.
Flow control setup was updated to RCS/CTS so that waking up from sleep mode
works properly.
|

|
|
AT+CFUN=4 will be used to go to standby mode.
|
|
Using AT+CFUN=1,0 so that we request to avoid resetting (<rst>=0). Works
properly when powering up after having put the modem in standby mode with
AT+CFUN=4.
Note that the power-up command will only be sent if the check to see if power-up
is needed requests it.

The NWSTATE field reports both available access technology and the
actual access technology in-use when a PS connection is active, so
report the actual access tech when it's available.
|
|
For connection failures, get additional error detail. Currently,
the only error codes that are mapped are the 3GPP TS 24.008 codes
for "Unknown or missing access point name" and "Requested service
option not subscribed" (which is sometimes returned for an invalid
APN).
(random fixes and cleanups by dcbw)

Otherwise make can't find build-time dependencies.

CFUN=4 disables the radios but still allows useful operations
like getting PIN lock status. So use that instead.
|
|
We need to ensure that the supports task always has the results of the probing,
no matter if the probing was just launched by the plugin grabbing the port, or
by a previous plugin. We do this during supports_port(), by propagating to the
supports task any possible previously cached probing results.
|
|
|
|
|
|
This is because the cinterion plugin can handle RS232 modes, and checking
support for them needs to have the vendor ID probed with AT commands, so
probing is almost always issued in this plugin. By sorting last, we let
other plugins check support first.
