I bought from Ebay 2 x Debugging UART Interface Terminal Cable for Raspberry Pi5.
They do not work and cannot work !
However it is possible to make them work by cutting the wires and swapping over TX and RX because as they are sold when plugged in TX will be connected to TX and the same with RX.
I have informed Ebay and the seller [dailyshop-28] but neither have chosen to do anything about it.
So unless you are happy to cut the wires and solder them together in the correct order don’t buy one.
