Cisco Certified Technician Practice Test

Typing 'Terminal Length 0' in HyperTerminal (or any terminal emulator connected to a Cisco device) modifies the terminal settings such that the router displays output in a single, uninterrupted stream rather than breaking it up into pages. By default, when a lot of output is generated, such as from commands that return large amounts of data, the terminal pauses the display and prompts users to press the spacebar to continue. Setting the terminal length to zero eliminates this pagination, allowing all output to be shown continuously on the screen without interruptions.

This command is particularly useful for commands returning extensive information, such as configuration details, or log outputs, as it provides a comprehensive view without the need for constant interaction.
