Hello, I just bought this router, main reason for my choice was the large flash and RAM size and its compatibility with open firmware.
It comes with buffalo firmware version 2.16. I opened the case and connected by serial converter (3,3V).

I've read a lot about firmware update, I have tftp already installed and I'd like to save CFE and maybe original firmware before trying anything but I'm not sure which command shoud I issue from serial, I know I should use the save command, but which memory area to save?
