I don't known if SIM900 works with my driver plugin. SIMCOM were not 
given us this information whereas we inquired them. It will be glad if 
someone check it.

The only main difference i see between the two plugins, it's the 
AT+CSCS="GSM" command. I don't exactly why there is this command. Maybe 
its a behavior need it to work correctly with the operator where the guy 
has wrote the code and done the test. If someone tell me how to check 
(with an AT command ?) if we need this command, I will do the job.

In the SIMCOM doc, I see this about AT+CSCS :

  - “IRA” : International reference alphabet.
  - “GSM” : GSM default alphabet; this setting causes easily software 
flow control (XON /XOFF) problems.
  - “UCS2” 16-bit universal multiple-octet coded character set; UCS2 
character strings are converted to hexadecimal numbers from 0000 to FFFF.

Right. My modem fires off a 'CPIN: READY' as an unsolicited 
notification. I will check the VENDOR_IFX or VENDOR_STE mechanism.

I guessed it will be nicer to have this but if you say no, ok, it was 
just an idea to have always a chips in same state at start and when 
ofono stops.
