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.
When connecting, and the modem isn't yet registered or denied, poll
both CS and PS registration state instead of just CS state, because
we're really more interested in PS state anyway. If at least one
of the CS and PS state checks is successful then proceed with the
connection.
It seems the Motorola Flipout with Android 2.1 doesn't like to return
configured PDP contexts via AT+CGDCONT?; it returns an error. It
seems to accept the rest of the dial sequence though, so just ignore
the error when reading existing PDP contexts.
Fix one more possible memory leak (left un-fixed by d3c2228 but not
caused by it) and ensure that modems that do want flashing get it
by default by adding the missing G_PARAM_CONSTRUCT so FLASH_OK
defaults to TRUE.
Flashing is a technique to break out of the data/PPP stream and
re-enter command stream (like +++) and MM uses it in the generic
paths in various cases. But devices that don't need it (ie, ones
with at least one AT capable port that won't be used for data)
now sometimes appear to have side-effects.
The Ericsson F5521gw firmware R2A07 resets port attributes like
echo and &C and such when the port is flashed, leading to
confusion on the part of MM. Since the Ericsson devices will
always have at least one free AT port they don't need flashing
anyway.
Generic code (like the QCDM CM/HDR checks) would determine the EVDO
registration state, which would then get blown away by the device-specific
registration state query method. Modems that have a more specific check
were fine, but generic devices that don't have more specific reg
state checks can simply rely on the generic checks done earlier and
don't need to update the EVDO state from real_query_registration_state().
Fourth and final in a series.
This fixes an off-by-one (septet) error in the calculation of the
amount of data to skip in the presence of a user data header, and adds
the test case from the wild that triggered it.
Second in a series. Builds on the previous by actually unit-testing
the sms_parse_pdu() function. Note that the dcf1 test does not pass
as the code is currently written.
The operator name/number isn't really tied to CS or PS registration, since
we retrieve it using AT+COPS. But when one of CS or PS became unregistered
the operator name and number would get cleared out. We only want to clear
it out when *both* CS and PS are unregistered. Fixes an issue with the
location API where location would not be reported when one of CS or PS
became unregistered, because the location bits want an operator name
before they return the location.
Some providers (CDMA Ukraine) apparently require a specific Rm interface
protocol, so add some Simple Connect dict settings for that and use them
when dialing. Obviously requires the connection manager to also have
support for sending the right bits down to MM.
The N900 has some odd serial characteristics in that it appears to
send pieces of the commands back for whatever reason, until you've sent
a few commands down to it. Almost like it's training on whatever
you send and needs a bit of input to figure out the characteristics.
Whatever. Just send the init command twice instead of failing when
the N900 barfs the first time.
1) use cfsetispeed/cfsetospeed like the TTY manpage suggests
2) ignore parity/framing errors since we're not using parity anyway
3) double-check that all our TTY settings were successfully set
Fixes a firmware hang on Option GlobeTrotter Express (GE0201 with
firmware 1.12.1Hd (Date: Feb 22 2007, Time: 09:20:28)) and makes
sense in general too.
Lifted almost entirely from similar code in NetworkManager.

Some modems only like the power-up command if not already in full functionality
mode. If the power-up is sent while already in full functionality mode, they get
rebooted and reseted.
With this changes, plugins can check whether they need the power-up and ask
the generic gsm code base to skip the command or not.
By default, power-up command (if any given) is never skipped.
Because the code was sending the USSD request with a "notify me via
unsolicited result code" tag, the response could come from any port,
and in was coming from other ports on various devices. But the code
expected the response on the main port, thus it got lost.
So turn the USSD response processing into an unsolicited command handler
instead, which allows us to process the response no matter where it
comes from. This patch also enables network-initiated USSD
notifications and requests since that's easy to add once the first thing
here is done.
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 feature is initially disabled for all modems, but plugins can enable it by
setting a value greater than 0 for the "max-timeouts" property when creating the
modem object.
Note that even if a plugin says it wants to be sorted last, the generic plugin
will always be the last one. Also, there is no order guaranteed between two
plugins that request to be sorted last.
Port probing is extended to also query for Vendor ID and Product ID. This allows
plugins to check whether the reported IDs are expected, and thus we enable
plugins to handle modems connected via RS232 ports (where udev doesn't give any
vendor ID) or modems connected via a USB adapter (where udev gives the vendor ID
of the adapter).
Note that this effectively means that a plugin which expects these kind of modem
connections will end up always launching port probing as they won't only rely on
the vendor ID reported by udev.
Previously plugins could only stop probing, *or* stop probing and
indicate support for a device. For the Alcatel X200/X060s debacle
we need to stop probing and indicate that the plugin does not
support the device at all.
