Let's make it simple.  Here's that section of my dtab file:


# If you have DL11s, you must give each line an explicit unit number instead
# of using a '?' as above.  If you use a '?', autoconfig(8) will start
# assigning unit numbers starting at 0 which will effectively move your
# console to that first line.  Start your unit numbers with '1'.
#
# cn    1 176500 300    5       cnrint  cnxint  # kl/dl-11 (on mvx11-aa)
cn      1 176500 300    5       cnrint  cnxint
cn      2 176510 310    5       cnrint  cnxint
cn      3 176520 320    5       cnrint  cnxint
cn      4 176530 330    5       cnrint  cnxint
cn      5 176540 340    5       cnrint  cnxint
cn      6 176550 350    5       cnrint  cnxint
cn      7 176560 360    5       cnrint  cnxint


Addresses and vectors were taken from the startup menu
presented by the 11/93 at power-up.
