It's only really used for phonebook and SMS PDU mode in the specs,
which we don't do yet, so if this is the only charset the device
supports we'll try to use it.
If the modem returns an error (like "+CME ERROR: incorrect password"
or even just ERROR) make sure we recheck PIN status and thus also
recheck the number of unlock retries instead of just returning the
error to the caller.

dbus-glib was not properly enforcing the 'access' permissions on
object properties exported using its API. There were 2 specific bugs:
1) dbus-glib did not enforce the introspection read/write property
permissions, so if the GObject property definition allowed write
access (which is sometimes desirable), D-Bus clients could modify
that value even if the introspection said it was read-only
2) dbus-glib was not filtering out GObject properties that were
not listed in the introspection XML. Thus, if the GObject defined
more properties than were listed in the introspection XML (which is
also often useful, and MM uses this quite a bit) those properties
would also be exposed to D-Bus clients.
To fix this completely, you need to:
1) get dbus-glib master when the patch is commited, OR grab the
patch from https://bugzilla.redhat.com/show_bug.cgi?id=585394 and
build a new dbus-glib
2) rebuild ModemManager against the new dbus-glib
Sometimes the primary mode will be 1X (and thus the Call Manager
will report 1X system mode) but the HDR subsystem will be registered
and idle. Figure that out and report that EVDO is registered too
in that case, since the modem will just flip over to EVDO when
the data call starts.
Apparently g_convert() can still return garbage that's not valid in
the character set you're converting to (???). But even if we don't
need to convert the operator name, make sure it's valid UTF-8 before
we go shoving it through D-Bus.
Found by jklimes. If some plugin already supports this port, it's
pointless to let Generic figure out if it supports the port since
we're just going to hand it to the other plugin anyway.
Some devices (Blackberries) always respond to AT+CREG with ERROR,
but will respond to AT+CGREG normally. Ugh. Handle that by
using the PS registration status from AT+CGREG if we don't have
a valid CS registration status at all.
The flash function could be called when the port was closed, and since
the flash function would only be canceled when the port was open,
it could trigger after the port object was destroyed.
Distributions should set dist-version at build time with the
package version and revision, so for RPM-based distros you'd
--with-dist-version=%{version}-%{release}
which will be printed out on MM startup to help debugging.
Since MMModem is an interface and doesn't store stuff like the
modem's physdev internally (since it's an interface) these things
are handled via GObject properties. And since g_object_get()
returns allocated values, we need to free the returned value
from mm_modem_get_device() after we're done with it.
There are some cases where flashing the primary port doesn't work
either due to stupid modem firmware or crappy kernel drivers. So
if we have a secondary port, try sending the PDP deactivation
command to the secondary port first, and if that fails send it
to the primary port after the primary port gets flashed. This
increases the chances that the +CGACT request will be successful.
Some modems (Huawei, ZTE) don't like +CGACT on the secondary port,
but when that fails, the code falls back to previous behavior of
flashing and sending CGACT to the primary port.
The argument passed to the handler is a GByteArray, not a
GString. Encountered with Option iCON Icera-based devices,
but could also be possible with Sierra devices.
