-
- Control Data has implemented RFC1139 in their OSI network called CDCNET
- (terminal servers, routers and gateways) and their CD4000 workstations.
- Both solutions are supported. They implemented in addition a command
- osiping which is modelled after the normal ping.
-
- Sun supports the special NSAP solution.
-
- What's about HP? We don't run OSI on our HP systems, therefore I don't know
- (but would be interested to know).
