send binary file over serial port with QSerialDevice

[ilpaso]

So what is the output from your program, "Writed text file" ?

Sorry there is an error:

if (r == quint64(data.size())) qDebug() << "Writed binary file.";

if (r == quint64(data.size())) qDebug() << "Writed binary file.";

To copy to clipboard, switch view to plain text mode 

this means:
"r" is the number of sent bytes
if r is equal to the file size the program prints "Writed binary file."

The error is: the program sends all the bytes but if there is a XOFF the device doesn't read all the bytes.
Now I've to find this XOFF answer, wait the XON signal and restart to write.
I thought the QSerialDevice manage this XON/XOFF but I don't know if it works.
