#Qt serial port rs485 update

QString QSerialPortInfo:: description() const Returns a list of available serial ports on the system. References to the values in the object become invalid. QSerialPortInfo:: ~QSerialPortInfo()Дestroys the QSerialPortInfo object. QSerialPortInfo:: QSerialPortInfo(const QSerialPortInfo & other)Д¬onstructs a copy of other. This constructor finds the relevant serial port among the available ones according to the port name name, and constructs the serial port info instance for that port. QSerialPortInfo:: QSerialPortInfo(const QString & name)Д¬onstructs a QSerialPortInfo object from serial port name. QSerialPortInfo:: QSerialPortInfo(const QSerialPort & port)Д¬onstructs a QSerialPortInfo object from serial port. Member Function Documentation QSerialPortInfo:: QSerialPortInfo()Д¬onstructs an empty QSerialPortInfo object. The QSerialPortInfo class can also be used as an input parameter for the setPort() method of the QSerialPort class. Each QSerialPortInfo object in the list represents a single serial port and can be queried for the port name, system location, description, and manufacturer. Use the static functions to generate a list of QSerialPortInfo objects. Provides information about existing serial ports. QSerialPortInfo(const QSerialPortInfo & other)

#Qt serial port rs485 update

If I remove the #ifndef statement, nothing is output to the terminal for an Android build.ДЇixed info update for FTDI devices on Android Gerrit Review:

We've hard-coded the port to be /dev/ttyUSB0, but it would be nice if the availablePorts() returned the port connected to the FTDI device. We're using an add-on module for Android in /system/lib/modules/ftdi_sio.ko, which recognizes the FTDI device and populates /dev/ttyUSB0, however this device isn't shown by QSerialPortInfo::availablePort(). When using an FTDI USB to RS485 device on an Android tablet, QSerialPortInfo::availablePorts() returns nothing, when a device is connected.
