Kann nicht zum senden von SMS über AT-Befehle

Ich bin mit QextSerialPort zu access-ports

#include <qstring.h>
#include <qdebug.h>
#include <QCoreApplication>



int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QList<QextPortInfo> ports = QextSerialEnumerator::getPorts();
    QextSerialPort *port;
    QString portName;

    int counter=0;

    //Navigate through ports untill you find huwawei USB dongle
    while(counter<ports.size())
    {
     portName = ports[counter].portName;
    QString productId= ports[counter].productID;
    QString physicalName = ports[counter].physName;
    QString vendorId = ports[counter].vendorID;
    QString friendName = ports[counter].friendName;


    string convertedPortName = portName.toLocal8Bit().constData();
    string convertedProductId = productId.toLocal8Bit().constData();
    string convertedPhysicalName = physicalName.toLocal8Bit().constData();
    string convertedVendorId = vendorId.toLocal8Bit().constData();
    string convertedFriendName = friendName.toLocal8Bit().constData();

    cout << "Port Name: " << convertedPortName << endl;
    cout << "Product ID:" << convertedProductId << endl;
    cout << "Physical Name: " << convertedPhysicalName << endl;
    cout << "Vendor Id: " << convertedVendorId << endl;
    cout << "Friend Name: " << convertedFriendName << endl;
    cout << endl;
    counter++;


    //Break if you found Huwawei USB dongle, assign the port to a new port

    if (std::string::npos != convertedFriendName.find("HUAWEI Mobile Connect - 3G Modem"))
    {
      std::cout << "found!" << std::endl;
      port = new QextSerialPort(portName);
      break;
    }
    }


    //Write and send the SMS
    port->open(QIODevice::ReadWrite) ;
    cout << port->isOpen() << endl;
    port->write("AT+CFUN=1");
    port->write("AT+CMGF=1 ");
    port->write("AT+CMGS=1234567");
    port->write("Hello Test SMS");
    //port->write("0x1A");
    port->flush();

    port->close();
    cout << port->isOpen() << endl;

    system("pause");
    return 0;

}

In diesem code, den ich versuche zum senden von SMS über AT-Befehle. Mein dongle ist ein Huawei-USB-dongle. Es ist bekannt als "MegaFone Modem" sowieso.

In meinem code, ich bin nicht in der Lage zu senden SMS eigentlich. Warum ist das so? Bitte beachten Sie, müssen Sie Bearbeiten die Telefonnummer, wenn Sie diesen code ausführen. Ich bin sehr neu in QT, USB-Programmierung und AT-Befehle. Ich selbst weiß nicht, ob ich den Zugriff auf den richtigen Anschluss, denn es gibt 3 Häfen gehören zu Huawei. Meine Ausgabe ist wie folgt.
