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).

To my understanding ISO folks in their June meeting more or less
adopted the long term solution of RFC1139 and will publish it as an
International Standard.  RFC1139 will then become obsolate.  Already
now the short term solution (eg. as implemented by Sun) should be
highly discouraged.
