In preparation for the multi-SIM setup, we need a way to tell whether
a given SIM card is active or not in the system.
On systems with one single SIM slot, the available SIM card will
always be active.
On Multi-SIM Single-Standby setups we may have multiple SIM slots with
multiple SIM cards, but only one of them will be active at any given
time.
On Multi-SIM Multi-Standby setups we may have multiple SIM slots with
multiple SIM cards that may be active at the same time. E.g. the QMI
protocol allows up to 5 different active SIM cards (primary,
secondary, tertiary...).
CHAP is almost universal nowadays, and so it is a better default
than PAP
Not changed for uBlox, that prefers an error if not specified,
and for Huawei, which uses NONE with user/pwd and has 2 CHAP choices
Extended the ModemManager Signal interface to include 5G signal
information for RSRP, RSRQ and SINR via libqmi. Also extended mmci
to print 5G signal info.
Instead of using the FALSE return of the method to indicate either a
fatal error (if result_error was set) or the continuation request (if
result_error wasn't set), provide a enum that has explicit states for
all three possible values (failure, success or continue).
Running NDISDUP=1,0 on an already disconnected bearer/context will
report ERROR, so we can really ignore the result of the command,
because we're anyway going to get the correct bearer/context status
later on with the NDISSTATQRY checks.
When a network-initiated event is received telling us that a
bearer/context is disconnected, we should handle and process it right
away, without thinking on whether there is going to be a
user-requested disconnect afterwards or not.
This effectively reverts the changes introduced in commit
21a5aaf4fe, which looks like was done to
handle synchronization issues with upper layers (e.g. with
NetworkManager or Shill).

We can safely cast the data in a GArray to gpointer first, and then
to the pointer type we require.

So far, we're really only interested in the "modem" and "pcui" ports.

It has the same exact format as MMBaseModemAtCommand, but its contents
are assumed heap allocated.
The only real purpose of this type is to allow defining static
constant MMBaseModemAtCommand variables without warnings when using
-Wdiscarded-qualifiers.

USB sticks only support voice if ^CVOICE returns 0. And to enable audio
streaming on the "Application" port (whatever is returned by AT^DDSETEX=?)
we need to send AT^DDSETEX=<port> after starting the call. After that
the serial port will send and accept signed 16-bit 8000hz PCM audio, or
whatever format is returned by ^CVOICE?.
This patch is a rework of the original implementation by:
Dan Williams <dcbw@redhat.com>
Calls created from property bundles are always outgoing, while calls
created as input events from URCs during runtime are always incoming.
This change makes it mandatory to provide at least direction of the
call when the object is created, leaving the number as an optional
property that may or may not be known in advance (e.g. it would be
optional only for incoming calls).
Instead of handling the URCs in the modem object and using the
MMIfaceModem as a bridge to report the status read from the URC to a
call obtained from the MMCallList... just handle the URCs in the call
object itself.
In order to detect state changes while we're in-call, we have to
monitor the standard connection errors we're used to, but have them
processed as URCs instead of as responses to ATD requests.
The most detailed call state transition flow for a new outgoing call
would be:
UNKNOWN -> DIALING -> RINGING -> ACTIVE
But, if the modem doesn't support reporting intermediate states
(e.g. DIALING or RINGING) then a successful start() should imply
getting into ACTIVE state right away.
For now, only the Huawei plugin implements the detailed transition
support, so make them configurable via call object properties.
