c70d6d565d Revert "cinterion: bail earlier if the plugin doesn't support the port"
This reverts commit 1e1bfbf1d8.

Aleksander says this might break RS232<->USB converter connected
Cinterion modems, so we'll need to handle this issue another way.

1e1bfbf1d8 cinterion: bail earlier if the plugin doesn't support the port
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.

0f6d1b2b42 nokia: N900 doesn't really need additional inter-character time
See 46d757faa7:

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.

46d757faa7 gsm: send init command twice to make the N900 happy (rh #583691) (lp:765516)
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.

2ca045f178 core: update some serial port settings
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

eae5d6c41b cinterion: enable power-off command to go to sleep/standby mode
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.

6e9d980e8c gsm: allow plugins to check if they need to issue the power-up command
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.

51c409d1eb ussd: fix reception, network notifications, and network requests
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.

f9f6d1dfdb plugins: propagate cached probing result to supports task
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.

4cb039e34a cinterion: always sort last the plugin
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.

5a2078a2a5 plugin base: include vendor ID and product ID retrieval during AT port probing
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.
