Best way to make sure all serial data is read

[jbsmith03]

Got there in the end!

char receivedData[DATA_LENGTH];
		if (arduino->isConnected()) {
			int hasRead = arduino->readSerialPort(receivedData, DATA_LENGTH);
			if (hasRead) {
				std::strcat(fullObject, receivedData);
				if (fullObject[strlen(fullObject)-1] =='}') {
					DEBUG(fullObject);
					fullObject[0] = 0;

Thanks for your help
