Problem in receiving the data from Bluetooth module

I'm sorry, my expected output in my previous post has both my inputs as well. Forgot to differentiate while posting. So the expected output is this.

LLL
OK

===
OK
LLL
OK
AT+INQ
OK

+INQ:00:1C:A4:14:7D:AA,"Sony Ericsson"
D4:C1:FC:3A:56:7C,"C1-01"
DONE

OK

The red ones are the Input commands that I send to the Bluetooth module.So I have to use Serial.write in this case, as I need to send the commands to my module. Please correct me if I'm wrong.
I'm am not well versed with coding, so kindly bear with my doubts.

while(Serial.available() > 0)
  {
    char inChar = Serial.read();
    if(inChar == SOP)
    {
       index = 0;
       inData[index] = '\0';
       started = true;
       ended = false;
    }

In this it reads the SOP and when it is done it deletes that from the receive buffer right?
inData[index] = '\0'; This is the one that deletes the stuff from receive buffer right?
