This sounds like it's exactly what I'm looking for.or you can use a Woobm USB Stick from mikrotik
Thank you very much for your time everyone.
Why a USB to Serial Converter? My PC has a USB port and the Routerboard has a USB Port. So is a Serial Converter really necessary? Why not using a USB to USB cable?So only way is to use usb to serial converter and after it appears in Ports, enable Console on it.
