The following items are not supported by this module:

• Terminal features, such as echo, control CR/LF, and so on.
• Text mode display for data transfer.
• Timeout and delay configuration while reading or writing.
• Notification on changing pinout signal.

Using the Module

Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

Building with CMake

Use the find_package() command to locate the needed module component in the Qt6 package:

find_package(Qt6 REQUIRED COMPONENTS SerialPort)
target_link_libraries(mytarget PRIVATE Qt6::SerialPort)

For more details, see the Build with CMake overview.

Building with qmake

To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:

QT += serialport
