SNA can run on multiple physical transports using the gateways. Serial, X.25, network adapter (specialized), etc are available. The SPD's specify what is supported. Like Johnny said however, finding some of this hardware may be a problem. One of the SPD's mentions an intermediate server that I have never seen/heard of. Sort of reminds me of the fun and games (not to mention expense) to get SNA to talk to Netware. -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE on behalf of Sampsa Laine Sent: Wed 10/21/2009 09:27 To: hecnet at Update.UU.SE Subject: Re: [HECnet] Next retro comms project?

I see several and it appears that many (if not all) require specialized hardware for the interconnection. A search for (vms sna gateway) will point you to the SPD's. -Steve -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Sampsa Laine Sent: Wednesday, October 21, 2009 08:34 To: hecnet at Update.UU.SE Subject: Re: [HECnet] Next retro comms project?

Setting up our own virtual X.25 PSDN tunnelled over IP maybe? Something crazy with SNA? SNA! SNA! :) I could set up Hercules here running MVS 3.8J ... ;) I'm sure the folks have been able to get SNA to work within the emulator. I set up Hercules and MVS once, but other than a novelty, I really didn't do much with it, because most of my associates wouldn't know a mainframe if it ran them over. I think it would be interesting to get something quasi-public (on HECmet) going.
