# Qt Serial Port

Qt Serial Port provides basic functionality for configuration, I/O operations, and getting and setting the control signals of the RS-232 pinouts.

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
