I thought someone listed a recommended pinout for the rj45/db adapters 
to use between a pc and the kxtd and tvs several years ago on this 
list.  there was even someone selling kits.  I just spent 2 hours 
searching the archives and couldn't find it.
Anyone remember it and can post it?   even Michaels  /before page 
doesn't show it anymore.  i tasked a tech to build a bunch of these and 
would like to stick to any informal standard.  i was looking at the 
cisco and adtran admin connectors, but they only need four pins.  i 
don't need the db9 to db25 pin out, have that down solid ;-)

i'm tending toward just using 2 to 2 thru 8 to 8 and then use 1 for 20 
on the rj45 plug.  

could dig up the old dec plug pinout, it was unique in that pin 3 and 4 
(of 6) was "ground".  the short made sure accidentally plugging into 
phone jack couldn't put 48 vdc on the rs232 terminal pns. pin 2 and 5 
were rx /tx, 1 and 6 were dsr/dtr, cable was crimped 1 to 1.  but 
crimping 1 to 6 (flip one end of cable over, like regular line cord) 
made a  crossover cable to test two terminals back/to/back.   might be a 
good idea, put cts/rts on pin 1 and 8 of an 8 pin rj45,  hey i like it.

thanks for the help!
