Here's some more details....the end users TN3270 to a specific IP address and are presented with a VTAM application selection menu; from there they can select which system and application they want to connect to. Some of these applications are in fact on the z/VM box itself, others are on different systems (e.g., z/OS) at different locations. The end users are not just doing a simple TN3270 connection to the z/VM box. I should have made that clear in my first note; sorry about that. ;-)
So it appears that they have two choices available: the EE solution Alan mentions here and the OSA SNA card approach that David B. suggests. Does anyone have any opinions on which would work better? Many thanks for all the responses; I appreciate it. Have a good one.
