Hi sudheer, echo will send commands. It will not display back the result. you can do something like echo atd*99# > /dev/ttyUSB0 || cat /dev/ttyUSB1 to see the response. But if the command is working then no need to see reply. There is no problem with sim. I think the reason airtel is working and docomo is not is bcoz of change in APN. edit the test-gprs.c and add docomo settings.
