9.3 How do I assign two class names to one DTC port designated for a printer? Sysgen won't recognize DTC devices, so modifying a class does not work there and I can't see a place in NMMGR to do it.
You can do what you are looking for on the Profiles screen in NMMGR. Modify the profile assigned to that LDEV and fill in the extra class names in the fields at the bottom of the screen.
