| QtSerialPort 5.2 introduces a few new features and improvements as well as |
| bugfixes over the 5.1.x series. For more details, refer to the online |
| documentation included in this distribution. The documentation is also available |
| online: |

| |
| The QtSerialPort version 5.2 series is binary compatible with the 5.1.x series. |
| Applications compiled for 5.1 will continue to run with 5.2. |

| |
| - [QTBUG-31966] Support has been added for non-standard Qt header installation |
| folder (e.g. on Red Hat). |
| - [QTBUG-33125] The generation of the forwarding headers now works with Qt 4 and |
| Necessitas. |
| - [QTBUG-33117] [QTBUG-33139] Fixed the compilation for Android with Qt 5. The |
| command line enumerator seems to work. |
| - Added support for non-standard BSD4 baud rates. |
| - [QTBUG-32173] Rewrote the documentation to more proper English than before, |
| and also improved the accuracy of the content. |
| - [QTBUG-33774] Document that the serial port parameters cannot be set before |
| opening. |
| - No more unnecessary syscalls (parameter settings, pinout signal query, etc) in the |
| backend when the port is closed. This also means no unnecessary errors are set. |
| - Removed the QtGui linkage for the command line enumerator example, so it now |
| links against QtCore and QtSerialPort only. |
| - More warnings when doing operations that require the serial port to be open, |
| but it is closed. |
| - The deprecated QtAlgorithm usage is removed. |
| - Some outputs in the examples are fixed to be more proper English; this |
| includes mostly typos, but also some comprehensive changes. |
| - New command line sync reader example available with screen shot and |
| documentation. |
| - New command line async reader example available with screen shot and |
| documentation. |
| - New command line sync writer example available with screen shot and |
| documentation. |
| - New command line async writer example available with screen shot and |
| documentation. |
| - The buildsystem now respects the configure run for Qt 5, i.e. pkg-config is |
| not used for finding udev again. |
| - [QTBUG-34429] Mark the data error policy obsolete. End users should stop using |
| this feature now. It may be removed later in Qt 6.X, and there is a warning now |
| if it is used. |
| - [QTBUG-34474] Replace the internal QTtyLocker with QLockFile from QtCore and a |
| small convenience on top of it to comply with the locking directories lockdev |
| also uses. |
| - The lock file usage has been extended to support Android as there is no direct |
| access to the usual Unix lock file system paths. The lock file is now placed |
| into /data/local/tmp. |
| - [QTBUG-35184] Mark the isValid() method in QSerialPortInfo deprecated because |
| it has no common use case. |
| - [QTBUG-35215] Mark the QSerialPort::Unknown* enumeration values in QSerialPort |
| deprecated because they have no use case. |
| |
| - QSerialPortInfo: |
| * [QTBUG-32684] VID/PID for USB Huawei 3G Modem is returned properly now. |
| * [QTBUG-32018] The port name and product identifiers now work for more devices |
| and scenarios on Windows. |
| * Linux: sysfs support was added for serial port information as a fallback for |
| udev. |
| * [QTBUG-34329] Support added for loading udev at runtime rather than linking at |
| compilation time. |
| * [QTBUG-32563] Motorola IMX support was added when udev and sysfs are not |
| present. |
| * Support has been added for the hard-coded device enumeration backend to get |
| information. Android uarts such as /dev/ttyHS* (High speed UART) and |
| /dev/ttyHSL* (Low speed UART) are supported by that backend. |
| * Support has been added for the hard-coded device enumeration backend to get |
| information. /dev/ttyO* (native OMAP UART) is supported by that backend. |
| * [QTBUG-35064] PCI support has been added to the sysfs backend on Linux to |
| support the enumeration of such devices. |
| |
| - QSerialPort: |
| * [QTBUG-32016] No "No such file or directory" error set after waitForReadyRead |
| anymore. |
| * [QTBUG-32017] Windows: Fixed the waitAnyEvent() method for the WAIT_FAILED |
| handling. |
| * [QTBUG-31964] The serial port enums are now properly tagged as Q_FLAGS. |
| * Added native serial port handle; it is now possible to do any custom operation |
| if not supported by QtSerialPort. |
| * [QTBUG-32680] Added API for handling the timeout errors when waiting for read |
| or write. |
| * Added a new error enumeration value called "NotOpenError". This can be used |
| for operations where the serial port is not open. This is also used internally |
| now. |
