QserialPort

[arturs]

Hi

I use the following code for finding available ports and checking if the ports are busy or not. Actually I would like to use only port which is not used by any aplication.

foreach (const QSerialPortInfo &serial,QSerialPortInfo::availablePorts()){
 
    qDebug() << "Name  :" << serial.portName();
if  (serial.isBusy())
    qDebug () << "OK";
    else qDebug () << "NOT OK";
}

foreach (const QSerialPortInfo &serial,QSerialPortInfo::availablePorts()){

    qDebug() << "Name  :" << serial.portName();
if  (serial.isBusy())
    qDebug () << "OK";
    else qDebug () << "NOT OK";
}

but It takes 35 sec Should it take so much time ?

Is it proper working ?
