Hai guys, I need a small help regarding receiver interrupt buffer. I need to capture the data from receiver interrupt ,for this i given buffer size is 200 in the UART interrupt handler.while getting the data from receiver interrupt i am getting only some bytes of data not full data .But i should have get the total data then what is the problem what should i have to do for that?

EX: 

  

when i will send the AT+HTTPREAD command to GPRS modem then it will gives the reply like this

+HTTPREAD:26
V:563VoltsP:3.312KWf:46Hz

Now here the problem is  i am getting only +HTTPREAD:26 data from gprs modem.The buffer only stores this data.

But i need get v,p,f values also.

Before i was checked in serial terminal there i got every thing perfect.
