Is it possible to make a GSM call using mobile terminal app..?
Actually, i try to make a call (communication) to modem through cellular network and try to access register (remote) of the device with Hayes AT command.
Did i need to connect my iphone to modem to make a data call before i can communicate with other modem?
Currently i use this kind of system using hyperterminal?
And now i try to replace the PC with my iphone, is it possible?

any buddy can help me?
