Accessing serial console on the Fon

Image:LaFonera_Hardware_Serial-Cable-Port_01.jpg Out of the box the foneros wireless router has Telnet and SSH turned off. By accessing the buit in serial console you can turn SSH on and access various settings and reflash the firmware.


Read on and you’ll find out how.


See LaFonera Hardware Disassembling for how to dissassemble your router. You will need to find the serial console. See the image below:

Image:LaFonera_Hardware_Serial-Cable-Port_03.jpg In order to connect it to your PC we need to convert the +3.3 volts from the Vcc of the router to the levels of your PC serial port wich operates at -12 to +12 volts.


For this you can use any kind of TTL to RS232 level shifter. These can be bought as kits or made from for example a phone data cable. Using a MAX 232 you can wire it up like this:

Using a dremel or a knife we need to cut out a hole for the Serial connector:

Draw along the connector to mark out where to cut:

If you use a dremel, use a low rpm so that the plastic don’t melt.

The finished cutout for the DB9 connector:

To access it you can use any terminal application. HyperTerminal ships with windows and it will do fine.Connect your fon to Com1 and Start hyperterminal from:

Start->Programs->Accessories->Communications->HyperTerminal .

You will need to set up communication settings to

9600-8-N-1 and no flow control:
