Have a read of @J-Hilk's https://forum.qt.io/topic/107618/qserialport-problem-with-waitforreadyread/7, and https://bugreports.qt.io/browse/QTBUG-78086. Yours refers to a different version of Qt, but presumably the devs are still having some trouble getting it right again even in 5.12.x? -
@JonB thank you for reply , I rolled back to 5.12.4 , it is fine.
