wavecom_initsettings is called _after_ the global initsettings,
i.e. we would loose anything that gsmd core has configured before
the AT+CFUN. This is particularly the case for AT+CMGF=0 (PDU mode).
wavecom/sysmocom: use AT@COPS if available, instead of AT+COPS2013-10-13T16:22:44+00:00Harald Weltelaforge@gnumonks.org2013-10-13T16:22:44+00:00urn:sha1:2aa67b809f5b06fb86a6f8dfc556bfb7c9169729
In certain sysmocom proprietary versions of the wavecom modem,
we have a non-blocking operator scan command called AT@COPS=?,
which we can use instead of AT+COPS=?.
The wavecom vendor plugin checks at start time if the command is
available. If yes, iti s used in case a libgsm client is asking for an
operator scan, instead of the standard AT+COPS=? variant.
some modems (like wavecom) require a CR after the Ctrl+Z in PDU mode2013-09-29T13:39:28+00:00Harald Weltelaforge@gnumonks.org2013-09-29T13:39:28+00:00urn:sha1:25c512a7b622daf2efcf67ab707d12ca09b172abpermit gsmd and libgsm to handle multiple instances2013-09-29T12:56:44+00:00Harald Weltelaforge@gnumonks.org2013-09-27T20:42:41+00:00urn:sha1:a72236a1d0effb1fe985f5685d40e6dc33ab65a3
By using differntly-named unix domain sockets, we can run
multiple gsmd instances in parallel.
make gsmd fail if the serial device disappears2013-09-29T12:56:41+00:00Harald Weltelaforge@gnumonks.org2013-09-27T20:48:56+00:00urn:sha1:292e73a08c3445b4aa96057e559dbcec44b0d8f7
If the serial device disappears (e.g. because of a USB bus reset),
there's no point continuing. We simply exit() gsmd and wait for
somebody else (init?) to re-spawn us.
wavecom: Fix unaligned memory access and silent stack corruption2013-03-17T09:40:26+00:00Holger Hans Peter Freytherzecke@selfish.org2013-03-16T21:05:31+00:00urn:sha1:6cdf70598ab71bad6b1aff95b9be9d972e581747
The parameters were uint16_t and we asked the libc to make a
store of uint32_t. So 16bit were written to the wrong part of
the struct and on ARM this is causing unaligned memory access.
Use the %hx to make a uint16_t store and avoid the above issue.

In some cases the modem might be stuck once we start up, so it's best to
re-initialize it at gsmd startup.
