Again, only required for various dialing features we don't deal with
yet.

Helpful when chaining a number of commands together when you want
to schedule the callback info only after all of them complete.

We don't really care about anything that came before.
|
|
Makes sure we build on Alpha, plus the right thing to do.

Device is functional without it; it's only required for stuff
we don't do yet.

For now; until Sierra releases their CnS documentation.
|
|
No more external users of it.

Some modems turn E1 on and off random (Huawei EC168C) and sometimes
the echoed command confuses things. We have a parser just for that,
so let's use it. It should be safe to use with devices that repect
E0 too.

Some ports we know we shouldn't use when we get certain responses
from them. Reading from these ports triggers kernel bugs (at least
on 2.6.31 and 2.6.32) relating to flow control in some drivers
(*cough* hso *cough*), so lets try not to aggravate the kernel too
much. This happens on Icera-based Option devices like the GI0322
(AT&T Quicksilver) for example.
(note: AFAICT this doesn't have any relation to the recent XON/XOFF
patch, since I get this problem without the XON/XOFF patch on both
2.6.31 and 2.6.32 as well)

The port is still connected until disconnect_done() runs, but by
this point we already know it's been disconnected so it's safe to
run the CGACT commands.
|
|
|
|
Longer entries first so we catch them before matching shorter
substrings. Previously, the strcmp() would have treated
PUK2 and PUK unlocks the same.
|
|
|
|
So don't crash if they don't.
|
|
|
|
Allow subclasses to override disconnect more cleanly so that
modem state gets handled correctly when the disconnect is complete.
Also fix up PDP Context ID handle (cid) so that subclasses can
get the previously-activated context ID when disconnecting, and let
the cid be an int since '0' is a valid context number.
For the generic devices, this also attempts to actually deactivate
the PDP context to ensure that the data session is terminated.
|
|
Reg status returned here is cached reg status, so it's pointless to
set it here again.
|
|
Ensure we send out signals when anything changes.
|
|
When a modem sends both CREG and CGREG in the same response packet,
the parser was failing to correctly distinguish which response
was being parsed, since the string passed to g_regex_match() is
the whole response including both CREG + CGREG.
