I have been trying with carriage return and line feed and yes i am working in text mode.

Now suppose i am getting a response from the modem as
/*****************************/
AT+CMGF="+919988179000"
>

This comes down to :-

65 84 43 67 77 83 61 34 57 49 57 57 65
65 49 55 57 48 55 52 34 13 13 10 62 32
/*****************************/

Now i will get this string on one go.
I will store this string in an array.

How will i know where to stop and start processing my array.
While i am receiving the characters i cannot perform the comparison ?
?? Or can i ??

in this i am getting the 13 and 10 in between the reply as well. Although i can manipulate then string once i have it but how will i know that i have to start processing of the string ?? ?????
