I don't know where the problem is Sergio but I can tell you that the following 
code definitely works and it may help you.

  port = new QextSerialPort("/dev/ttyUSB0");
  port->setBaudRate(BAUD4800);
  port->setFlowControl(FLOW_OFF);
  port->setParity(PAR_NONE);
  port->setDataBits(DATA_8);
  port->setStopBits(STOP_2);

  port->open(QIODevice::ReadWrite);

  port->setRts(false);
