Hi.

I am preparing my PDP-11/73 for my exhibition at the VCFe. I wane get
the DHV11 (M3104) and a four port DLV11J colne to work. At the moment I
get upon boot:

autoconfig: warning: more than three handlers for device cn on line 38.
dhv ? csr 160440 vector 310 didn't interrupt.
ra 0 csr 172150 vector 154 vectorset attached
ra 1 csr 160334 vector 764 vectorset attached
rx ? csr 177170 vector 264 skipped:  No CSR.
tms 0 csr 174500 vector 260 vectorset attached
ts 0 csr 172520 vector 224 attached
cn 1 csr 176540 vector 344 no address found for kl/dl-11

Extract from /etc/dtab:
# grep '^[a-zA-Z]' /etc/dtab

What is wrong with the "cn" devices? 

I checked the CSRs of the DHV11 and the DLV11J cards with the "show
qbus" command on a MicroVAX 4000-200 to be sure that the CSRs are where
I am expecting them:
