read and write in serial port

[neda]

I wrote a .net program.It worked very well likes to Hercules_3-2-6 Application and qt program worked after opening the program.
Is it bug of Qt 5.5.1 ?

I added this line for handle error port.

voidMySerialPort::handleError(QSerialPort::SerialP ortErrorerror)
{
qDebug()<<"Error:"<<error;//I added this line
if(error==QSerialPort::ResourceError)
{
showStatusMessage(serial->errorString());
closeSerialPort();
}
}

Result of run program:

Error: 0
"Connectedd"
Error: 6
"\x00"


Just sometimes I have error 6.
How do I fix break condition error?

Nohow. It is HW/driver issue.

UPD: Future Qt 5.6.0 won't be process the Parity/Frame and BreakCondition errors anymore. So, you can try QtSeriaslPort from 5.6.0 branch.

Of course,My program is problem because other programs (C# .net , Hercules) work very well.
My problem is bug of QSerialPort?

So what? Maybe they (those programs) do not trace the EV_ERR event flag. This flag coming from the device driver, and QtSerialPort < 5.6 handles this error when it is occurred.

You problem is bug of HW/driver of device.

Thanks you very much.
Your answer was a big help for me.

serial->setDataTerminalReady(false);
