I am receiving about 90 bytes on the serial port. but arduino has the serial buffer of 64 bytes only. because of this limitation i am unable to receive further bytes.

char c;

void read_response()
 {
     while(Serial.available > 0)
     {
    c=Serial.read();
    Serial.print(c,HEX);
    Serial.print(",");
    }
 
}

i tried using above function to read the serial data, but it is able to read only 64 bytes.

another approach i tried as follows:

char rxdata[]={};

void read_response()
 {
     while(Serial.available > 0)
     {
    int len= Serial.readBytes(rxdata,90)
      }
 
}

with this approach also i was receiving only 64 bytes

Serial.flush() also don't work as it waits for current transmission to finish. & i do not have control on transmission end. transmitter is sending 90 bytes continuously.

please give me some suggestion.
