One of those supports SNA over IP. I'm not sure which. I think Dave might know a bit about this. I've not done direct SNA over IP. Note that Hercules can make virtual 3270s appear as tn3270-protocol ports over IP. This works quite well. The MVS (or VM, etc) system thinks they're connected via an establishment controller. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
