Use console mode to upgrade

If you have a VT100/dumb terminal system you can optionally run the upgrade in console mode, also known as character user interface (CUI) mode.

The upgrade steps in CUI mode are the same as those in GUI mode.

The standard CUI mode keyboard commands are:

• 1: progress to the next screen.

• 2: return to the previous screen.

• 3: cancel a screen.

• 5: re-display a screen
