i know that...
my question is how to handle response send by modem in c?

Read the response into a array using UART interrupt. Formatting of data is needed to discard unwanted data like '>', "OK", '"', etc... Post an example of response.

respone of AT+CIPSTART command is
OK
CONNECT OK

first OK comes then after sometime CONNECT OK comes....so how to check this?

Read OK and CONNECT OK into an array. Terminate the array with null character to make it a string. The final string will be "OKCONNECT OK". Confirm by printing this string on UART or LCD. Then declare a similar string and use strcmp(str1, str2). If both strings match function returns 0. If 0 you can take that right response is received else response is wrong.

Do similar thing as it was done for AT_CIPSTART. Use Serial interrupt to read the response into an array.
