Hey Thomas,
Supported and Allowed modes are modified to be bitmasks of MM_MODEM_MODE

so that it is faster and easier to maintain, keeping in mind the
different specific needs of the current plugins.

It would be great if you could do that, indeed.

Hi Dan list,
Would it be a good idea to alternate QCDM port probing along with the AT
port probing?, something like:

* If timeouts, try QCDM
* If timeouts, try again AT command(s)
* If timeouts, trya gain QCDM
* If timeouts, try again AT command(s)
* If timeouts, failed

Hi Eric,
The additional error detail allows us to know that a connection failed
because of an invalid APN. Also, when handling access technology
changes, report the technology in use if we're connected. Finally,
avoid using CFUN=0 when disabling the modem.
A small thing to fix in the patch.
All the stuff in the protect-callbacks branch looks good, please push.
I couldn't trigger crashes on a number of devices just pulling them out
in the middle of a tight loop hammering the modem for info. Good work.
This has been pushed to both git master and MM_05.

My understanding is that the whole support for caching capabilities

From a cursory reading of the bug reports you cited it seems like some
