I had not seen this documented anywhere else...
I just found out that the WRT350N router's WAN port has four pins (not the RJ-45 network pins but on the opposite side). I traced the 4 pins and confirmed that they do indeed connect to the serial pin-out inside of the router.
So anyone know where to find a RJ-45 jack has the 4 pins on the opposite side? (like the side that you push to release the jack)
