VM/Pass-Through Facility (PVM)

Product Number: 5684-100 Release 2.1.1

Last Updated: 2024-02-09

VM/Pass-Through Facility (PVM) is a communications product used by VM users to access other systems (such as VM, MVS, OS/390, VSE, and AIX). PVM lets you access, log on, and use another system in defined PVM and SNA networks as though your display station is directly connected to that system. All you need is a user ID for the system you want to access. Once you have connected to a target system, you may communicate with that system as though you are working on that system.
