yes i have checked the modem with hyperterminal, manually by typing following code …
AT+CMGF=1 response “OK” was returned.
AT+CMGS=”9030888888″. response “>” was returned.
Then I typed my message, after that I Pressed Cltr+Z to send the message and it was sucessfull
But when i have dumped the code into Microcontroller then its not sending SMS ….!!!
Can u plz suggest any further modification ……waiting for ur reply ….
