In response to my previous post about UART access on the Alfa AWUS036NHA, I got a nice email from Jim Ewing about the DWM-W034, an ath9k_htc device that apparently is embedded inside HDTVs and readily available for $10. He found the TX/RX pins on the board, and it looks like it would be a bit easier to put a socket on one of these compared to the Alfa since there are no pesky chips nearby.

With his permission, and so that this information doesn’t get lost to the sands of time, here’s the pic he sent me. Enjoy!
