The above tape contains a DECNET.DOC file that states the following: | 1.8 DECnet-20 Operation | | DECnet-20 consists of the monitor and front-end components, and | user-mode utilities. DECnet-20 resides within the TOPS-20 monitor. | The DN20 is not required for DECnet communications over the NIA20 and | the CI20. So maybe you just need to find the right monitor and user-mode utilities. :) HTH, G. These are indeed the tapes I've used, and I am indeed running the correct monitor... $VDIR *DCN* PS:<SYSTEM> AN-MONDCN.EXE.1;P777700 647 331264(36) 1-Jun-88 21:21:17 BROOKS $VDIR MONITR* PS:<SYSTEM> MONITR.EXE.1;P777752 647 331264(36) 1-Jun-88 21:21:17 OPERATOR
