When data is written by QSerialPort, there is still data in buffer or not complete to write data even QSerialPort::bytesToWrite is 0 after calling QSerialPort::write.
- Using cross cable.
- Create data
- Using creadersync and cwritersync which are contained examples for Qt SerialPort.
Actual: cwritersync is terminated even though it has not completed writing, then read data by creadersync is dropped.
Expected: Get actual timing to complete writing data.
