-> "nobody uses RS232 anymore!"
Somebody needs to update the hand writing on the wall, although the physical hardware may be an RJ-45, the RS232 protocol is still used on headless devices and probably other things. I use minicom more than I wish but it's still required.

Even if you did have an RS232 port on the box, the serial drivers for
CentOS 7 have
never worked correctly. I had an application using RS232 that worked
perfectly
under CentOS 6, and then worked intermittently under CentOS 7, and
failed miserably
on CentOS 8. The handwriting on the RedHat wall says, "nobody uses
RS232 anymore!"
I moved the app to a Raspberry Pi 3B+, using the USB serial adapters,
and it works
perfectly again.
