GSM SIM responce on LCD problem

[dhanajaya]

Sir I have tested for the following code with PC hyperterminal its working fine for both send and receive the GSM response , but GSM SIM 300 with PIC 16F877A its working only for sending commands is fine but like sending message and dailing its ok but I want to check the whether its response is OK or error .So it will display only for Carrage return(CR) and Line feed (LF)values i have checked the ASCII table. because i have adding 0x30 to GSM data so it will display like =: on LCD so it will in the ASCII table but not display like OK

please help me... what are the instructions to do this getting like OK . I think it will not given OK from GSM SIM response please check my code and correct it ...

   buffer= '\0';

      {
      buffer+= 0x30;
      lcd_goto(0x00+i);

      }
   while(1);

void clearBuffer()
      {
     for(i = 0;i < 95;i++)buffer = ' ';
     }

LCD display for only =:

i think its formate like \r\nOK\r\n but it will only display for \r\n

please help me sir...
