My brother gave me a FONERA router which I will make into a WLAN link station soon. Here are the important links I have collected:

I intend to use the FONERA router as remote little box to serve a WLAN link, but also to handle a packet radio Terminal Node Controller. Because it is a little hard to have software running on it, I want it to make its ttyS0 available over the network to my core box... '''ser2net''' seems an interesting way to go.

Hacking it is extremely simple. Just follow the instructions given [http://sodoityourself.com/accessing-serial-console-on-the-fon here] and connect a level shifter correctly and you will get access to the Redboot BIOS. The only little difficulty I ran into was to keep any kind of flow control switched off. If HW flow control should still be "on", you cannot write to the console and entering CTRL-C will not cause Redboot to come up.
