Sorry, misunderstanding. This is definitely hobbyist use in my case, and I was just guessing (incorrectly it seems) that the network support I wanted was only available in the commercial version. Being that that's not the case, I for one think that either XM or XD support would be awesome, since I still use RSTS/E v8. :) But I understand it not being a priority.

Why, is this for commercial use? I mean, it won't address this specific problem since I've never finished the XM: emulation in E11 (no real interest from users, but I've been meaning to get it done anyway it just on principle, especially since I rewrote the Ethernet link code for dual-DR11W IPLs a while back to make it general enough to be able to encapsulate protocols like DDCMP so that connections between like E11 machines would be easy), but hobby users can use the Demo version of E11 (for Linux or any other host OS) for free, indefinitely. It has some cripples, but it's still pretty luxurious compared to any real PDP-11 system I ever had... John Wilson D Bit
