Hi venkat, for running from init.rc simply put your command in a script and add the script as a service. You can follow instructions here :- http://afewe.wordpress.com/android-arm-development/use-point-to-point-protocol-ppp-in-android/ Just modify the non commented /system/bin/pppd /dev/ttyUSB0 115200 mo...... line with your command and add this in your init.rc file
service pppd_gprs /etc/ppp/init.gprs-pppd user root group radio cache inet misc If you run pppd and rild together what error are you getting? if your modem is getting disconnected then i may not be able to help bcoz i don't have the same modem. But if the problem is that you are getting above error log then the problem is that after at+cgdcont=1... your modem is not giving OK response it is giving new line characters and timing out. Did you want it to send a newline character after "CellOne" ~ *^**M. *if not, then that may be the culprit. Or may be your modem is not able to complete the request before the timeout.
