Here are the pinouts for the Fonera 2100 and 2200.

2200

Refer to the pictures above to figure out how to connect the cable to the Fonera. The serial cable will create a COM port on your computer such as COM1, COM2, COM3, etc.  Make sure to specify that COM port in your terminal program (like Hyperterminal).

Here are the settings you should be using for your terminal client:

Bits per second: 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow Control: None

After that, hit "OK" and power on the Fonera.  You should then see some text on the screen.  Hit Control + C to access RedBoot, but make sure to do this within 5-10 seconds. 

Here's what a succesful connection will look like:
