Any comments ? :(

Before, I tested with 1.6.

And, today, I tried with 1.12.

And, I've got some troubles at modem power up... During the 3 first 
start, ofono was blocked after sending a command. Here 2 pastes :

------------------------------
[...]

------------------------------

As you can see, It's not always at the same moment. After that, I can't 
send AT command anymore, the modem seems to be locked.

I try to debug this and found the CMUX and CMUXSRVPORT ports. I can have 
a DIAG port, so, I try to configure it. I stopped ofono, the modem and 
sent these commands :

------------------------------
AT+CMUXSRVPORT=0, 0
AT+CMUXSRVPORT=1, 5
AT+CMUXSRVPORT=2, 1
AT+CMUXSRVPORT=3, 1

+CMUX=0
------------------------------

------------------------------
AT+CMUXSRVPORT
--------------
< port >: virtual com port
0 – 3 currently support 4 virtual com ports index from 0 to 3

< service >: valid service
0 – DIAG Service
1 – DATA(MODEM) Service
5 – NMEA Service
------------------------------

And now, each time I start ofono and power up the modem, it works. No 
lock. Hum, I'm disapointed. I didn't think theses commands could fix the 
problem. And, no messages in diag or NMEA tty. Hum... And moreover, now 
all SMS I send are received. No failure. So good news, but, I'm troubled.

After grepping on ofono source, I see some driver plugins do a CMUX set 
(calipso, phonesim). Maybe, I need to execute a CMUX set ??? It can be 
important ?

Nevertheless, I don't understand why I have problems with this T-Mobile 
SIM card and not with Vodafone for example...

Anthony.
