Hi Venkat,
1. Still i am not able to access the internet, when i run init.gprs-pppd
manually i am getting error : Connect script failed
but i am able to make phone call and receive.
2. I tried as you explained in previous mail for accessing internet, by
manually writting c program for sending AT commend and i used below
mentioned commend for pppd
pppd /dev/ttyO0 115200 asyncmap auth connect 'chat -v "" AT OK ATE0 OK
AT+IPR=115200 OK AT+CGDCONT=1,\"IP\",\"TATA.DOCOMO.INTERNET\" OK ATD*99#
CONNECT' nocrtscts defaultroute modem updetach
but not succeed, Please can you tell me detail procedure how you able to
access the internet on Devkit8000 using GPRS8000, how you wrote and
executed C application and pppd commend and how you set dns1 and dns2.
Thanks and Regards
Devindrappa
