I've verified the DB9<->DB25 does not cross, so I have rewired, and

My new adaptor is:
Berg DB9
B 5 GND
F 3 TX
J 2 RX
E-. Interlock bridged
M-~ Interlock bridged
Powering on the 11/34a gives me the same... nothing at all, but as I
suspect the 11/34a is halting somewhere, this is probably quite
reasonable.
My thanks, Steve, for getting me a little closer.

header. Currently it looks like this:
BERG ? ?DB9
B ? ? ? ?5 ? ?GND
F ? ? ? ?2 ? ?RX
J ? ? ? ?3 ? ?TX
I -think- this is right, but I'm not positive. If I'm doing something
stupid, I'd sure love to have someone point it out.
I built a cable like the adapter you're describing here for a DL11-D
and it looks like the same sort of deal. For a terminal, I think you
want RX and TX the other way around (unless you're using a crossed
cable from your adapter to the terminal, of course). You also need to
connect the "interlock" pins too (E and M for EIA/RS-232).
