set Qextserialport port

[David_]

Hi,

I am using QextSerialPort.I mean I would like to use it.
I have a "QextSerialPort port" variable.
I sent a message like this:

port->write(message.constData());

But I have problem to get the answer.

I want to get 64 bytes in 200ms.
So I did this:

port->bytesWritten(64);
if (port->waitForBytesWritten(200)){
} else {
}

Of course it didn’t work. ByteWritten is protected. I don’t know how I can use these functions.

Thank you for any kind of help.
David.
