I got myself a PL2303 adapter, which should work. The Pi itself is a 4 Model B.
My brief google suggest that is USB to RS232. RS232 voltage levels will kill a Pi. As will 5vTTL serial. Make sure it's 3.3v TTL before using it.
You may also need to enable dthe UART in config.txt.
Guides for setting up a headless pi involve creating an image that still use the framebuffer as a console, but with the network preconfigured and ssh as an additional backdoor. That's not useful at all. I'd like the pi to work without keyboard and graphical output. Once that works, I can continue to boot OpenBSD normally.
max_framebuffers=0 was suggested somewhere, but that doesn't appear to be documented here.
Being able to use the framebuffer as an auxiliary device is fine, but it shouldn't be the console output.
Any ideas? Have a nice day!
What's the problem with having the HDMI/framebuffer console? Security? Disable autologin and make the USB ports inaccessable. Lost RAM? If that's an issue you've got bigger worries than the small amount of RAM used for the text console.
I'm not sure disabling the console on tty1 is enough. You may also need to disable any gettys running on other VTs as well.
Now, that said, you appear to be using OpenBSD which I've no experience of so your milage may vayr
