That's unfortunate design of the QSerialPort class (QProcess has the same problem), and might be fixed in Qt 6, but not before that, due to the API stability guarantees Qt makes. The new-style syntax connects cannot be used in this case, as they cannot be used if there are slots or signal overloads with the same name but different signature.
QObject Class | Qt Core 5.12.3 Detailed Description. The QObject class is the base class of all Qt objects.. QObject is the heart of the Qt Object Model.The central feature in this model is a very powerful mechanism for seamless object communication called signals and slots.
