Hi,
Am unable to make a call through GSM modem. If try the same command using Hyper terminal its working fine but not able to dial using controller. sending message is working fine from my controller can you help me to suggest what may be the problem. i written code using C.
How do you think that is going to be possible?
You haven't said what GSM modem you're using.
We know nothing about your code, and we know nothing about your hardware - other than, "it doesn't work".
