I'm trying to get the WRV54G serial port access, as I need to get to the CLI interface. I hope to be able to enable telnet, that way. I did solder the pins to the board. I do have an operational serial voltage switcher. It does work correctly as Samsung HDD serial terminal. I did replace zener diodes from 2.7V to 3.3V, in order for it to work with 3.3V TTL serial port. The WRV54G serial pinout seems to be: RX/TX at pins 1/7, ground at 4 and 6. But, I'm not getting any output in the Hyper Terminal. According to my research the serial port should be working with 115200 N 1, software flow controll. I do not know if it is enough to turn the router on, to get some output on the serial port. Perhaps, I have to enable the serial port first, somehow. I'm still working with the latest Linksys/Cisco firmware.
