Thanks, but as you noted, it's not hard to find info about remote
serial port consoles.  My question was about doing a similar thing
over Ethernet.  That is, with a single Ethernet cable between the
local NIC and the remote NIC, not necessarily on a real, many-port
network, and definitely without telnet, ssh, and other network
services running -- so that it works from single-user mode, working
just like a serial console.  I'm sure the Ethernet support is mostly
there in the kernel, but maybe something fairly simple is missing from
whatever reads /etc/ttys; eg, to know which NIC is to be the console
port), and maybe there needs to be an ethernet-getty (similar to
telnet, but which needn't even use IP addresses).  And maybe a
"ethconsole" addition to "comconsole" and "vidconsole" in
"/boot/loader.conf".

Maybe I'm missing something, but it seems like this would be a often-
used feature, especially as RS-232 serial ports will probably be
disappearing from new motherboards in the next few years.
