When your terminal is dumb or you request GRUB of hiding the menu interface explicitly with the command @command{hiddenmenu} (see section hiddenmenu), GRUB doesn't show the menu interface (see section The simple menu interface) and automatically boots the default entry, unless interrupted by pressing ESC.
When you interrupt the timeout and your terminal is dumb, GRUB falls back to the command-line interface (see section The flexible command-line interface).
