Hi all, I have the above mentioned device and have been using it for a number of years to access the console ports on several of my vintage computers. It also communicates with the serial ports on a couple of older UPSs that I still have in service. It has worked flawlessly up until a couple of months ago. At that time, I replaced my old primary router with a new one. This new router is an ASUS and runs an ASUS specific version of WRT. This new router seems to broadcast a number of packet types that the IP stack on the Annex was not designed to handle. The buffers containing these packets appear to be leaked and the memory loss eventually causes the Annex to hang hard. This happens about every 40 hours. A power cycle will bring it back. A bit of googling seems to indicate that I am running the latest official firmware (from 1995?). I can't seem to find any web discussion of the Annex more recent than 2004. I wondered whether anyone here might know of some trick or some small remaining community of users of the Annex. I know that it has something to do with traffic from the new router because if I isolate it on a subnet by itself it still runs fine with no memory loss.

Thanks, Bill S.
