XON/XOFF connection with QtSerialPort

[oldFox64]

Hmm, if I don't use waitForBytesWritten after write and waitForReadyRead before read, the communication doesn't work properly. That means that these functions are checking the control chars XON/XOFF (as I said, my firmware, the receiver, sends me XON's and XOFF's chars) ? If so, I think it would be a good idea to specify it in the documentation, don't you?
