Thank you.

A piece of wire between pins 2 and 3?

No thanks. This was just clearing up an oddity in the operator test
procedure where you go into local mode and type ESC Z (the ident
sequence) and then observe a single character on the screen. The
response string would be something like ESC / K, where the final letter
varies with model of terminal and installed options. However, the
terminal swallows ESC / on the way back, and just displays the final
character. You can't try this in VT52 mode on later terminals because
they swallow the entire sequence (which in their case is ESC / Z).

Case closed, thanks Jerome.

You may have to turn the unit off in order to effect the change, I'm not
sure. You'll find the switch definitions in the DECscope User's Manual
and the Maintenance Manual, both of which are online.
