Complete rebuild of precompiled QT binaries necessary to applay patch?

Hi all

I've some troubles with QModbusSerialMaster: If I Change the my current baud rate (19200) to a higher one (115200 or 921600) I get always a responce timeout. After some Google search I found this Bug Report:
https://bugreports.qt.io/browse/QTBUG-53767
In my oppinion the calculation for the timer would always results in 0 if the baud rate is higher than 1100. So there is something weird. I hope that this patch would solve my Problems.

Do I really have to delete the ct creator and mingw Installation, download a clean Version (no prebuild one), Change the file Content to applay this patch and build qt by Hand? Or is there a better way? Because I would have to do this on several Computers...

Best regards,

QtCreator can handle any number of Qt versions, so if you want a custom built one you can still use the same creator.

Cheers,
