Definitive serial library

[PaceyIV]

I add this method to query available ports name, on both Windows and GNU\Linux

#ifdef _TTY_POSIX_
#include <QDir>
#endif
 
 
const int MAX_COM_PORT = 20;
 
// Query available SerialPort name
QStringList MySerialPort::availablePortsName()
{
    QextSerialPort testPort;
    testPort.setBaudRate(BAUD115200);
    testPort.setFlowControl(FLOW_OFF);
    testPort.setParity(PAR_NONE);
    testPort.setDataBits(DATA_8);
    testPort.setStopBits(STOP_1);
 
    QStringList portsName;
    QString testPortName;
 
#ifdef _TTY_WIN_
    for (i=1; i<MAX_COM_PORT; i++)
    {
        testPortName = QString("COM%1").arg(i)
        testPort.setPortName(testPortName);
        if (testPort.open(QIODevice::ReadWrite))
        {
            portsName.append(testPortName);
            testPort.close();
        }
 
    }
#else // _TTY_POSIX_
    QDir dir("/dev");
    QStringList filters;
    filters << "ttyS*" << "ttyUSB*";
    dir.setNameFilters(filters);
    dir.setFilter(QDir::Files | QDir::System);
    QFileInfoList list = dir.entryInfoList();
    for (int i=0; i< list.size(); i++)
    {
        portsName.append(list.at(i).canonicalFilePath ());
    }
#endif
 
    return portsName;
}

#ifdef _TTY_POSIX_
#include <QDir>
#endif


const int MAX_COM_PORT = 20;

// Query available SerialPort name
QStringList MySerialPort::availablePortsName()
{
    QextSerialPort testPort;
    testPort.setBaudRate(BAUD115200);
    testPort.setFlowControl(FLOW_OFF);
    testPort.setParity(PAR_NONE);
    testPort.setDataBits(DATA_8);
    testPort.setStopBits(STOP_1);

    QStringList portsName;
    QString testPortName;

#ifdef _TTY_WIN_
    for (i=1; i<MAX_COM_PORT; i++)
    {
        testPortName = QString("COM%1").arg(i)
        testPort.setPortName(testPortName);
        if (testPort.open(QIODevice::ReadWrite))
        {
            portsName.append(testPortName);
            testPort.close();
        }

    }
#else // _TTY_POSIX_
    QDir dir("/dev");
    QStringList filters;
    filters << "ttyS*" << "ttyUSB*";
    dir.setNameFilters(filters);
    dir.setFilter(QDir::Files | QDir::System);
    QFileInfoList list = dir.entryInfoList();
    for (int i=0; i< list.size(); i++)
    {
        portsName.append(list.at(i).canonicalFilePath ());
    }
#endif

    return portsName;
}

Thank you very much PaceyIV, I'll play with you class!
It's a pity that QT4 doesn't have a built-in serial class, I can't understand why.

In this way, everybody should reinvent the wheel... And there are many people (like me) who aren't so skilled to implement the library themselves.

There is a big chance a serial class from Qt Extended will make it into desktop Qt.
