qt application interacting with GSMmodem in windows

[jjbabu]

Hai to all,
i developed GUI for my application using Qt.first i developed my application to send data directly using serial port.now my requirement is the data should be transfered through GSMmodem which is connected to serial port on my PC.

is there any useful tutorial or sample examples on how to write source code for connecting and sending AT commands to the GSM modem?

please provide some examples regarding this issue,
thanx in advance.

This has nothing to do with Qt and the Internet is full of useful descriptions on what you seek.
For example: http://pda.etsi.org/pda/AQuery.asp. It is free for download. The only condition is to register.
And for more information you should search etsi.org.

Ok. Go to http://pda.etsi.org/pda/queryform.asp and search for the ETS 300 642 standard.

marcel,
i downloaded the information and read that.on that link they provided info regarding AT commands syntaxes,but i know AT commands well.
Actually my doubt is how my application initializes(provide attention) to the GSM modem.after dialing the certain number,how can i transmit the data to the recipient number.
plz give some clear info regarding this,
thanx a lot
