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. Qt Signals & Slots: How they work | nidomiro So if you call the Signal of the QObject the method generated by Qt will enqueue the command to call the Slot in the Event-queue of the other QObjects thread. The Signal-method returns immediately after enqueuing the command. To ensure all parameters exist within the other threads scope, they have to be copied.
