From: Peter Lothberg <roll at Stupi.SE> For what it's worth, Ersatz-11 (my PDP-11 emulator) also supports DDCMP over UDP, and I don't consider it ugly at all -- it's a very neat fit. (E11 can also use TCP, or actual real async DDCMP over serial lines, and there are the beginnings of support for DDCMP on sync lines too but usable hardware for that is rare.) John Wilson D Bit
