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.

Add run-time changing of gsmd log level via libgsm/libgsmd-tool2013-03-15T10:07:12+00:00Harald Weltelaforge@gnumonks.org2013-03-15T10:07:12+00:00urn:sha1:3ec111676ff9e34058b3bf2e482a236f341c10ebvendor_wavecom: Reset the modem on initialization using AT+CFUN=12013-03-15T09:32:51+00:00Harald Weltelaforge@gnumonks.org2013-03-15T09:32:51+00:00urn:sha1:4c14b6eb4183905dea8f0a2cea695cebb174815f
In some cases the modem might be stuck once we start up, so it's best to
re-initialize it at gsmd startup.

This avoids having to have another client program which then passes
messages from gsmd into gpsd. Rather, gpsd can directly receive the
messages via UDP.
