quick hack to use an arduino or msp430 launchpad as a serial passthru to reprogram a fonera?

Question

The fonera has 3.3V tx/rx logic, I have a launchpad and an arduino, can i use any of the cable/boards to reprogram or access the serial on a fonera?

fonera serial info is here : http://www.dd-wrt.com/wiki/index.php/LaFonera_Hardware_Serial-Cable-Port#Accessing_serial_console_on_the_Fon

I am specifically asking about methods and boards not covered in this previous Q: Can I use an Arduino as a USB to serial interface?

Answer 1

Yes, the answer is the top post in Can I use an Arduino as a USB to serial interface?

Use the FTDI chip by wiring your Fonera to the TX and RX pins on the Arduino and run a sketch on the Arduino which doesn't use those pins.
