Just to make sure I'm understanding this fully - this is the Berg

I think
there's one thing you've forgotten, but it would only affect
input from the terminal. And that's that you need a jumper wire on the
Berg connector to connect the output of the RS232 receiver (for the RxD
line) to the input of the UART (the reason for this jumper is that you
can fit a different jumper to connect the current loop circuit to the
UART).
One thing that would help you a lot with the console cable: check out
the prints for the DL11 (M7800) on Bitsavers (thanks, Al!). It has a
table of the connections, including the jumper Tony mentions. These
cables aren't all that uncommon, so you might be able to pick one up on
ePay or from someone on this list. -- Ian
