Yes, this was my first source of confusion (I was expecting the OFW
to more resemble my Voyager/U60/SB2000).

I'm using tip(1) over a regular serial port.

Note, however, that neither "U-Boot" (which is part of the banner)
NOR "u-boot>" (which is the prompt that appears) exists anywhere in
this text!

So, it seems like there are a boat load of prompts -- "u-boot>",
"->", "ok" ...  And, nothing that seems to summarize ALL of
the pertinent environments in which you can be interacting with
the box.

Note, for example, the different responses to the "version" command
(no doubt, this is "old" -- but HOW old?  Which versions of Slowaris
might it support -- without a firmware upgrade?):
