it's not quite clear if your Qt application is supposed to be the master or the client.

Either way, for Slave use:
Qt5:
https://doc.qt.io/qt-5/qmodbusrtuserialslave.html#details
Qt6:
https://doc.qt.io/qt-6/qmodbusrtuserialserver.html

for Master:
Qt5
https://doc.qt.io/qt-5/qmodbusrtuserialmaster.html
Qt6:
https://doc.qt.io/qt-6/qmodbusrtuserialclient.html
