This is perhaps purely an aside but it's a somewhat relevant one. Many boards these days do actually ship with a standard UART at port 0x3F8 but the bracket isn't provided. I didn't set out to do it but the middle-of-the-road Gigabyte AM5 board I bought just two years ago had a header for one. The bracket with a 9 pin port was something like 4 bucks on Amazon. 10-pin IDC on one end, ribbon to a bracket with a DTE port on the other. It's worth eyeballing motherboard manuals; I've come across as many as not with a header for these and they save a ton of headache.
