Is there documentation that explains how to configure this kind of

OpenBSD?
I never had problems with it: just as normal LAN.
Yes, but there are caveats and it requires manual configuration.
Depending on the OS there are different sorts of gremlins to look out
for when configuring the connection.
Point to point. Hmm. I used slip+tcp/ip instead of zmodem to
transfer files between rs232. Now remains ppp, a litle more
complicated.
When I said "point to point" I meant an Ethernet connection that goes
directly from one machine to another (with a crossover adapter if the
NIC can't be configured to do this manually or via autodetection). Such
a connection would not pass through any hub, switch, or router.
I don't know if that was clear.
I've used SLIP+TCP/IP or PPP+TCP/IP over RS232 in the age of dialup
ISP's. And also for a months when I was trying to access my personal
workstation on my university campus, from home.
But I just followed instructions to get the darn thing working and I can
not remember how it is configured or how I would get it to work now.
THIS would certainly be an interesting and useful thing to learn about.
Also, I would like to learn how to use ZMODEM (and other protocols) to
transfer files again. I haven't used it since my BBS days.
^ All of this kind of knowledge needs to be documented thoroughly.
Hardware specifications need to be made clear too. Preferably all open
source. I'm keen to do this (but first is getting my web site and CMS
set up). Knowing how to quickly set up such a communications link can
rescue an emergency scenario.
But the primary use case now is to be able to directly interface between
a laptop computer (running OpenBSD) and an out of band management
interface on a server (BMC/IPMI).
