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.
