From there my : knowledge takes quite the nose dive. What previous versions of MPE had : ARPA or at least TCP/IP available as a purchased product? And, if you : can remember, what's the product numbers? About tcp/ip, the first version (on classic hp3000) was available in MPE/V UB-MIT (or UB-delta-1). This was back in 1985..1986. When MPE/XL was born (i.e. MPE/XL 1.0), it came out with NS/3000 that runs over standard TCP/IP stack. Please don't come back saying that NS is a proprietary product and not standard tcp/ip.... I'm tired of this. Yes, NS is proprietary but the underlying TCP/IP has always been the same de-facto standard tcp/ip and conforms to MIL specs and RFCs 793, 792 and 1122. I.e. any MPE/XL or iX system out there has a standard tcp/ip transport if it has LANLINK installed (usually with NS or ARPA services). FTP/iX from HP was introduced with MPE/iX 2.2 in 1990. NetIPC API to TCP was there all the time and BSD sockets API was added in MPE/iX 4.0. Also, another common misconception is that NetIPC and BSD sockets cannot talk to each other -- wrong. One has to remember that neither of these two is a protocol, only an API to the top of TCP and there's nothing preventing you from having a NetIPC sockets application talking to BSD sockets application over TCP/IP across internet. Product numbers... hmmm... maybe someone out there can remember those... I tend to know the technical side but the product numbers have never been my strong side....
