despite much reading of cisco documentation and a bunch of
experimentation, I was unable to manufacuture a management cable for
my client's screwed-up cisco 806 router. I could find no one in my
city who would give me the time of day to borrow a cable ("sniff ...
we don't deal with the soho stuff").
So to save someone else buying a router on ebay before they know for
sure if their router is completely bronked, here are the pinouts for
part number 72-3383-01.
This information is gathered from direct observation of the above part
number, and confirmed by making a working management cable from a
db9/rj45 adapter and a modified ethernet cable.
DB9 RJ45
(PC) (console)
1 ----- Not connected
2 ----- 3
3 ----- 6
4 ----- 7
5 ----- 4
6 ----- 2
7 ----- 8
8 ----- 1
9 ----- not connected
If you can build the above from "rolled" ethernet cable and an
db9-rj45 converter as shown in the cisco documentation*, you're way
cleverer than me.
Make a note when you are wiring your custom RJ54 cable -- this is not
a "reversible" cable -- one end must go in the db9-RJ45 adapter, and
the other must go in the console port of the router.
Another alternative is to buy a db9-rj45 adapter that is not yet
"assembled". Then you could do the pinouts in the adapter to suit a
standard ethernet cable. You'll have to figure that out yourself from
the above and maybe some references like those following.

This is the adapter I would use if I was doing a second time, and I'd
wire it to use a standard ethernet cable (cost was about 70 cents)...
