And I just read Glen Slick's response about the pinouts, where he listed
them fully. Apparently, DEC never did modem control on any of the ports,
so it's just 2,3,7 which are useful anyway.

Wow..

Hmm. Interestingly enough I just searched through both the 11/93 and
11/94 manuals, which I referred to before, and neither actually seems to
have the pinouts for the serial ports. Oh well.
The console is on a DB25, with a very standard RS-232. I hope everyone
can manage to get that one right.
For the DE9 connectors, they actually also follow the RS-232 standard.
For a connector without the modem control, all pins are in the first 9
anyway, so no problem. If you want full modem control, there is one
signal - DCD I think, which is on pin 20 in the RS-232 spec. On the DEC
DE9, I think that one was moved to pin 8. But someone should check that
out, in case they actually want full modem control. From: Roe

Can anyone point me at the pinouts for the
KDJ11-E pdp11/93
DB9 rs232
connectors for the extra 7 (simulated) DL11s?
Alas, documentation on the 11/93-94 seems to be very scarce on the
ground.
(And, just for grins, the page in the 11/94 User Guide which has the
section -
1.2.6 - which talks, however briefly, about that panel - pg. 1-4 - is
missing
from all the online copies of that manual which I checked.)
