I built one Rs323 to RS232 adapter during the first lock down this year. I
had this project on my todo list since 3-4years already. I connect it to
the GPIO pins and have a serial console, where I can see exactly
everything. It works great. It helped me debug and setup the TFTP boot. But
of course you can also buy a ready to use one. Pay attention on the chipset
and manufacturer. There is tons of fake and buggy crap out there. There are
also Serial to IPv4 converters, so that you can access your serial port via
internet. AFAIR they are RS232 (12V) so perhaps a TTL level shifter
(323-232) and a Serial to IPv4 is what you are looking for.
I am not aware of any additional software (besides setting up the serial
port on the RPI4)
