I am trying to get DECnet working on SIMH running VMS 3.7 using a DELUA. I have already fixed one bug in the DELUA emulation that gave a fatal controller error on startup, but now I get this: $ @startnet %RUN-S-PROC_ID, identification of created process is 00020011 %OPCOM, 25-JAN-2013 22:15:27.94, message from user DECNET DECnet starting %RUN-S-PROC_ID, identification of created process is 0001000C %NCP-I- NMLRSP, listener response - Operation failure, detail # 30 Executor node = 9 (VMS037) %SYSTEM-F-ABORT, abort $ Can anyone tell me what this means? After that the line bounces up and down with line synchronisation lost errors. Regards Rob
