Description
In synchronous Read this code doesn't work. waitForReadyRead always return false, "buff" will be empty always.
while (m_serialPort->waitForReadyRead(TOUT_MS))
{
buff.append(m_serialPort->readAll());
}
Instead async Read work properly. Signal ReadyRead generated properly.
In 5.12.9 , 5.6 all work correctly.
