now i want to send the first 3 line to that serial port and the letter start from h means its sends (seria.write ) to another serial port

See QString::startsWith()

@Christian-Ehrlicher Yes i want to read line by line first and after that if the string is = h means
its need to write on the another serial port
i tried this code but its not works

QTextStream stream(&inputFile);
      while(!stream.atEnd()) {
      QString strline = stream.readLine();
      m_lines.append(strline + QString("\r\n"));
if QString::stratsWith("h"){
  QString strline = stream.readLine();
      m_lines.append(strline + QString("\r\n"));
}

      }
      }
      checkAndSendData();
}

First this code does not compile - so please don't say 'I tried this code' ...
Second - this code does not write anything to any serial port.
