Especially for Telit HE910 it is not enough to wait for
entering a PIN code.
If we do not wait for #QSS: 3, subsequent commands,
like +CMER will report SIM BUSY and the network registration
atom will be removed as a consequence.
If device probe and removal happen in short succession, it's possible
that the idle handler registered in the probe function doesn't run before
the device is removed. In this case, the idle handler needs to be
unregistered so that it does not run and try to access the data that's
destroyed during the removal.
Encountered a problem of CME ERROR 14: SIM busy on Alcatel and Huawei modem.
The Huawei modem has a ^SIMST unsollicited sim state indication, but not all
Huawei modems support this.
So poll the SIM state, as was already done for ZTE modems.
The Wavecom Q2XXX support broke in commit 72ce19bf3e.
This is because at_cpin_cb called decode_at_error with final and not
with OK. This lead to an error being set in the error variable and the
new code returns early when an error is set.
The addition of the terminator in at_sim_probe for Wavecom broke in
git commit ac524be99f because
terminators can not be added on cloned chats.
Move the addition of the terminator from the atmodem to the wavecom
plugin. Use the same terminator for Q2XXX and the normal Wavecom
class. The WAVECOM terminator has been tested on a Q2XXX modem.
Apply the CPIN quirk for both WAVECOM and WAVECOM_Q2XXX inside the
sim.c file. Introduce needs_wavecom_sim_quirk to handle it for
WAVECOM and WAVECOM_Q2XXX.
We encountered the problem of CME ERROR 14: SIM busy on ZTE modems.
ZTE modems don't use SIM notification to check SIM state.
We poll SIM ready state before confirming PIN is entered.
Use AT+SPIC for obtaining retries remaining for SIM PIN / PUK
AT+SPIC Retries Remaining to Input SIM PIN/PUK
+SPIC: <pin1>,<pin2>,<puk1>,<puk2>
Parameters
<pin1> Times remained to input chv1
<pin2> Times remained to input chv2
<puk1> Times remained to input puk1
<puk2> Times remained to input puk2
This driver will be used by CDMA modems to support PIN
management and IMSI retreival.
EF entries for CDMA modems cannot be implemented without
manufacturers specifications.
