Hi igorpadykov,

Thanks for information, i gone through that document, as of now i am checking in Linux PC 14.04 and 12.04 ubuntu versions.

I am getting only /dev/ttyUSB0 but in document they given /dev/ttyUSB1 and /dev/ttyUSB2 also but any have they mentioned /dev/ttyUSB0 is for AT commands. But as i mentioned above only device details i can able to get.

Thanks & Regards,
