At the moment I’m trying to flash my Sitecom WL-351 router with the OpenWRT firmware.
First steps have been made by opening the case and soldering wires to the serial port holes of the PCB.

I only use the GND, TX and RX pins and left the VCC connection unconnected (the router will provide its own power as will the computer from which the firmware needs to uploaded).

You cannot simply connect these wires to a serial port (if I have had one) but should use a USB to RS232 TTL Converter Module when you want to connect the serial ‘port’ of the router to the USB port of the computer. Luckily I had one USB-BUB II (used to flash my JeeNodes) which works perfectly. (For more information visit this OpenWRT page)

Once the two devices was connected by wires I started putty to open serial connection, for the Sitecom WL-351 the baudrate is 57000 (extra parameters 8N1). When the console is started I switched the power toggle of the router and …. yes I saw meaningful lines of text coming from the router.

On the OpenWRT site I used this page to get started.
