Visual Studio 2022 dotPeek C#  After dotPeeking Uniden BC_VUP_V3 to VS solution it is quite easy to do some mods for it, e.g. modifying it to write firmware to file without Uniden radioscanner connected to COM port. Mainform.cs comment out CheckScanner() SelectCom.cs comment out !usscRemote.CanOpen ... replace if and else with code in else section usscRemote.cs TransferPacket, comment out ComPort.WriteLine and ComPort.ReadLine and add e.g. System.IO.File.AppendAllText(..., Packet ...
