Currently, the module API contains two classes: QSerialPort and QSerialPortInfo

QSerialPort is the base class of the module and provides a set of basic methods and properties to access resources on serial ports.

QSerialPortInfo is a helper class. It provides information on the available serial ports on the system.

 

 

Below is a simple example of main.cpp :

1. #include <QtCore/QCoreApplication>
2. #include <QtCore/QDebug>
3.  
4. #include <QtSerialPort/QSerialPort>
5. #include <QtSerialPort/QSerialPortInfo>
7. QT_USE_NAMESPACE
9. int main(int argc, char *argv[])
10. {
11.     QCoreApplication a(argc, argv);
13.     // Example use QSerialPortInfo
14.     foreach (const QSerialPortInfo &info, QSerialPortInfo::availablePorts()) {
15.         qDebug() << “Name        : “ << info.portName();
16.         qDebug() << “Description : “ << info.description();
17.         qDebug() << “Manufacturer: “ << info.manufacturer();
19.         // Example use QSerialPort
20.         QSerialPort serial;
21.         serial.setPort(info);
22.         if (serial.open(QIODevice::ReadWrite))
23.             serial.close();
24.     }
26.     return a.exec();
27. }

Note:
CONFIG += serial port
QT += serialport
must be the first or second line in your .pro file.

.

QextSerialPort *port = new QextSerialPort(<portname>, <Querymode>);

to add the setting like databit, stopbit, etc syntax is as follows:

port->setBaudRate(BAUD_9600);

port->setStopBit();

port->setDataBit(); etc..
