Many GSM mobile phones (like Nokia , Erricsson etc) has got in built GSM Modem or modem emulation which operate through GSM AT command set on serial interface.

I have tried a Nokia phone for this purpose. I have connected mobile to PC COM1 port through mobile data cable & used hyper terminal for comm.

When I give AT commnad at is echoed from phone but OK response doesn't comes.
Even it is taking AT&V COMMAND it is responding with result (phone parameters)
How can I get OK response and can I issue (or how) GSM commands for sending SMS through PC?

Hi Anil,

You might not have the right type of cable. Nokia phones generally have two types of cable interfaces ... one allows the phone to be used as a modem with AT commands ... the other is for special purpose programming (logos/provisioning).

However, the fact that it is responding with some information is a bit weird.

You could try sending ATE0V1 to the phone ... this turns off echo (E0), and enables verbose responses (V1).
