here is the code for my project ..the problem is that when i uplode it in arduino uno...
it and when i sens a string LOAD1ON there should be a resopnce LOAD1=ON
but i wont recive this response on terminal

I am not sure if arduino works this way.. or I am thinking how will it work. maybe the below statement waits for 10 bytes to be recevied?
I feel reading should be somewhat like this:
char c[10]={Serial.read()};
I feel reading should be somewhat like this:
for (i = 0; i < 10; i++) {
while(!Serial.available());
c[i] = Serial.read;
}

the logic is ....seems to be simple and correct...
but not tested........
because....unfortunately....a..late....reply.....
i have completed the..code...with another logics..in arduino..n workes fine......
will try to use u r logic in another program.......
Thank u......for the reply.....

Well I doubt the correctness of the same. even if compiler create code for such statement. either it will end after reading 10 bytes compulsorily in order to fill the buffer or it will read just one byte. In either case if your command will not match with expected.
e.g. you give LOAD1ON = 7 bytes, arduino might wait for 3 more bytes before start processing.

I agree Ajay
According to this page
http://arduino.cc/en/Serial/Read
Serial.read() only reads one byte.
There is a
Serial.readBytes() function which may be what was intended.

m about to complet this project but stuck in a GSM AT command
when we send a
AT+CMGR=1 the modem send the first sms that is recived with the time, date, caller ic ...etc then at last the required sms
but any AT command that will only send the required sms to konw
or
first sms to deisplay then other all details of sms...

At command CMGR will give all the data that's how it's designed. There is no way to get just the SMS text. However you can add a start and end character to recognise the desired text from SMS response.

ok...so what modification ..
or what type of instruction ..have to write..in embedded c or arduino

@gaurav, sorry for delayed response 
festive season.
You can add special characters to your sms as I mentioned, e.g.
$LIGHT1=ON#
wait till you get $ after sending CMGR command and then to find end of message look for #. I think you can easily do it in C something like:
easy enough
