Also, the class QSerialPortInfo is invoked to enum QSerialPort:: Direction flags QSerialPort:: Directions This enum describes the possible directions of the data transmission. Qt Serial Port Examples, This example shows the main features of the QSerialPort class, like configuration, I/O implementation and so forth. For example, QSerialPort::write() returns immediately. QSerialPort emits a signal when the operation is finished. Operations are scheduled and performed when the control returns to Qt's event loop. Shows how to get information about serial​ QSerialPort supports two general programming approaches: The asynchronous (non-blocking) approach. Terminal Example, Shows how to use the synchronous API of QSerialPort in a non-GUI thread.

Shows how to receive data asynchronously over serial port. Shows how to get information about serial devices in a system. Shows how to use the synchronous API of QSerialPort in a non-GUI thread. When the data is sent to the serial port, Blocking Slave Example. Qt Serial Port Examples, QSerialPort emits a signal when the operation is finished.
