Mike Lu used the four unused wires on one of the RJ45 Ethernet connectors to add serial communication on his RT-N12 router. This allows him to use the serial port for debugging and still use that port for network connection. He used a circuit to output the correct serial signals and connect them to the unused RJ45 pins. Then he used a special adapter to separate the RS232 signals from ethernet. This allow him to use the serial connection without modifying the router case.    [via]
