This is my mini PC on which i'm running OPNsense https://www.aliexpress.com/item/4000627539297.htmlIndeed I have a secondary COM 2 port which is DB-9 but the UGREEN USB to RS232, USB Serial Cable DB9 is not good for me since the second COM port is male DB-9 so I need a female DB-9 ending on the other side similar to this one https://www.aliexpress.com/item/32922249681.html?spm=a2g0o.cart.0.0.7c4e3c00k6MeLi&mp=1I also heard that Ugreen has very good products and I also was looking at this https://www.ugreen.com/products/usb-2-0-to-rj45-console-cable which uses the well known FTDI chip instead of CH340. I have asked them if this cable can be used as null modem and I'm waiting for an answer from them.Thanks for support
