I don't know. It just sounds "weird" to me. I guess that I'm still stuck in the "green screen" mindset <grin>. Can't have two green screens connected to a single coax. I can envision doing this. I even envision a TN3270E "fan out" server. I.e. the "fan out" server connects to the mainframe. The real people connect to the "fan out" server. They all see the same TN3270 screen. I guess the "fan out" server would allow the user to select (or specify via the LUNAME parameter in the connect request) which mainframe screen (LU or address) they want to view. > > I would never expect VTAM to allow multiple connections to > the same LU, > it's not designed to allow it, but it does allow multiple > connections to > the same host.
