SNA or non-SNA

How you break out of a session depends on whether you have an SNA or non-SNA terminal.

If B appears in the lower-left corner of your screen, you have an SNA terminal.
If A appears in the lower-left corner of your screen, you have a non-SNA terminal.
If neither A nor B appears in the lower-left corner of your screen, ask your administrator what kind of terminal you have.

To break out of a session on an SNA terminal

Press the Attn key either once or twice in one second. The TPX Menu is displayed.

To break out of a session on a non-SNA terminal

Press the Reset key. You can then issue a command.
