Not reading data from hardware device using qextserialport in Mac OS

[GoogleCodeExporter]

I included include(src/qextserialport.pri) in my pro file and added src 
directry to my project 

I created one Dialog(Member to main class) to configure serial port and I popup 
from main Window an I used the following code in OK button 

void SerianConnectionDialog::on_btnOK_clicked()
{
    if (!port->isOpen()) {
        port->setPortName(ui->portBox_2->currentText());
        port->open(QIODevice::ReadWrite);
    }

    //If using polling mode, we need a QTimer
    if (port->isOpen() && port->queryMode() == QextSerialPort::Polling)
        timer->start();
     this->accept();
}

In My main class I concted the ready read of function 

void MainWindow::connectSerialPort()
{

    if(QDialog::Accepted== dlg.exec())
    {

        this->port= dlg.port;
        ui->led->turnOn(port->isOpen());

        timer->setInterval(40);

        connect(timer, SIGNAL(timeout()), SLOT(onReadyRead()));
        connect(port, SIGNAL(readyRead()), SLOT(onReadyRead()));
    }
}

And I coded to display data in a texedit

void MainWindow::onReadyRead()
{
    if (port->bytesAvailable()) {
        ui->textEdit->moveCursor(QTextCursor::End);
        ui->textEdit->insertPlainText(QString::fromLatin1(port->readAll()));
         ui->textEdit->insertPlainText(QString::fromLatin1("\n"));
    }
}

But not showing any data from device. Any error in my code ?

The port showing open in Main class but not getting data to textbox
when I run CoolTerm application it showing the data correctly

I have no idea, but you can give a try to 

port->readAll().toHex()

or add some qDebug() to code your code.
