Instead of this

QByteArray msg = buff;

QByteArray msg = buff;

To copy to clipboard, switch view to plain text mode 

try

QByteArray msg = QByteArray::fromRawData(buff,numBytes);

QByteArray msg = QByteArray::fromRawData(buff,numBytes);

To copy to clipboard, switch view to plain text mode 

or

QByteArray msg =  port->read(numBytes);

QByteArray msg =  port->read(numBytes);

To copy to clipboard, switch view to plain text mode
