Data read by the 2D scanner before establishing a connection with the 2D scanner

[Hiprox]

Hi, I am using this library to work with a 2D scanner. The problem is that when I don't connect to the COM port, but scan some code with the scanner and then connect to the COM port the scanner is running on, the data it read before connecting comes from it. How can this be fixed? Where to look in the source code?
