Yes, you hit ALT-SysRq, and that puts you into the configuration menu.
You can completely remap the PC keyboard just like the DEC one too,
which is a nice bonus.

I'm using a genuine Digital RS-423 to serial converter, which I assume
does the right thing.  The 510 has RS-232 so I could try that instead.

Yeah, I'm a little surprised that curses code still does that kind of
thing. On a software terminal on a fast machine, you just never notice
it's happening. I think the serial code needs fixing, but I still don't
see why the shells don't simply issue what they want.

I used to have one of those, and I miss it. Except for the relatively
slow SCSI, it was actually a decently fast machine. I seem to remember
that it heated the room a lot though.
