Hi Chin,

What is the programming language you are using to make the AT command call?
For example, if you are using Java, you can make a call like this:

String strReturn = objSerialPort.strSendAT(”AT+CNMI=2,0,0,1,0\r”);

The return value from the modem will then be stored in the variable strReturn

i am using the window hyper-terminal program to send sms via a GSM modem. every time i key in the At-command. Like at, atz, and at+cmgf. It will give a (ok)return code, so how can i going to verify this (ok)return code in my program. For an example: my program have to make sure the first At-command is key in and receive a (ok) return code then it will proceed to key in next At-command. Might i know where is the return codes store at?
