The signal readyRead is never emitted, even if data is sent to the serial port from a connected device.
The member bytesAvailable returns 0 even if data has been sent to the serial port from a connected device.
The only way to have the signal readyRead emitted is receiving some data while waitForReadyRead is waiting.
In Qt 5.13.0 all worked as intended: readyRead was emitted as soon as the new data was sent to the serial port from a connected device.
The "Simple Terminal" example can be used to reproduce this bug.
I've tried the one from Qt 5.13.0 and works fine with a test device (38400 | 8n1 | no flow control).
The one from Qt 5.13.1 simply outputs nothing.
