Using the Serial Cable
Using the Serial Cable Step 1: Turn the router over and remove the top two rubber feet. Step 2: Split the case and remove the top piece using a flat head screwdriver or similar instrument. The reset button may fall out. Keep a close eye on it so you don't lose it. Step 3: Connect the serial header to the serial cable as follows: Note: You may need to use solder. Step 4: Start any application to communicate with it, like GNU screen. Configure adapter to use the following settings: Baud rate: 115200 Data bits: 8 Parity control: none Stop bits: 1 Handshaking: none Example: screen /dev/ttyUSB0 115200 # Make sure your user is part of the dialout group. Power on the router, wait for a line like one of the following and interrupt the process of loading a kernel: Autobooting in 1 seconds (for most TP-Link routers, you should enter tpl at this point) Hit ESC key to stop autoboot: 1 (for 8devices Carambola 2, use ESC key) Hit any key to stop autoboot: 1 (for D-Link DIR-505, use any key) Step 5: Review the full documentation in u-boot_reflash on the root of the source code CD included with the router. There is additional documentation on flashing the router here.
