Hey Ken,
I am trying to get the serial connection to work on my old AuraHD (with a cracked screen). I've got the serial connectors hooked up to a TTL2USB connector, have a program maintain a connection to it at 115200@ 8 N 1, but to no avail!
The serial setup is the same as the one I used to put Openwrt on my router, so there should not be a technical problem there. Any ideas? I tried both serial headers.
