If you want to disable the Cisco IOS more ... prompt (for example, when listing router's configuration with the show running command), set the terminal screen length to zero with the terminal length 0 exec-mode command. To change the terminal lenght permanently, use the length lines line configuration command, for example:

line console
 length 0
line vty 0 4
 length 0
