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)

This is only true for the WRT350N v1 (USA version), the v2 (European version) doesn't have a conenctor there. Oh, just noticed, the WRT150N (v1.0) has the same pins in place, too.

My aplogies for any unwanted necromancy, but I'd like to find a cable for this apparent serial port. The other thread that mentioned this had a link to some cable on eBay, but the auction is long since gone and there's not even a picture left.

Think about if it is really worth to spend hours to try and find such exotic piece of hardware, while it takes just about 10-15 minutes to solder some pins or wires to the internal connectors.

Since I would have to buy wire and a DE-9 plug anyway, I might as well look for the specialized cable. Much neater than having to open the box, too.
