hello sir

i m interfacing gsm modem to my microcontroller.i need to send sms through it. i am using AT commands for that.the command to send sms (AT+ CMGS) terminates with ctrl-Z.now in my program i hav tried all ways to send ctrl-Z at end of my sms.but it takes this as a character or string only.also i tried with ascii value of ctrl-Z but
of no use.
i am able to see the transmitted commands on hyper-terminal through serial interface & also on serail window while debugging. the commands are as follows with 2ms delay between each of them. 
AT ,, AT+CMGS = mobile no. , “message to be sent ” ctrl-Z
please help me

Hi Anurag

Have you tried sending "rn", it is nothing but a Ctrl-Z command. Also you have to wait for the ">" response from module; message should be sent after receiving this. An "OK" repsonse, at the end, will assure a successful delivery.
