I've successfully modified my RV042 so that I can use the serial port to get into the console of the device. I'll be posting a page on how to do this soon, keep in mind that it will invalidate your warrenty and its not risk-free. I may also make customized firmware or modify the existing firmware for the RV042. One reason is because the RV042 (the one I have) randomly reboots every several hours to days. It may be heat-related or it may be related to something else. Being able to see the console when this occurs is very valuable. Also once you console in, you have more control over things such as VPN endpoints. I'd like to know how many people are interested (in non-official firmware) before I get very involved into this. If not alot of people are interested, then I'll probably use the existing firmware and just login via console.
