# Qt Serial Port

Qt Serial Port provides the basic functionality, which includes configuring, I/O operations, 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.
- Configuring timeouts and delays while reading or writing.
- Pinout signal change notification.

To use the serial port in your application, add the following include statement:

     #include <QSerialPort>

For information about available serial ports, use the following include statement:

     #include <QSerialPortInfo>

To use the module with cmake, use the `find_package()` command to locate the needed module components in the `Qt6` package:

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

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

     QT += serialport
