SmartSwitch 1800 Asynchronous PAD – is the default welcome message, displayed when the terminal is switched on and DSR and DCD become active. When the node boots, the software looks for a file named BANNER.TXT (which does not exist when the software is sent to the customer). If the file is not present, the default banner is dis- played. Any text editor can be used to create BANNER.TXT, which can consist of up to 256 bytes of ASCII and [Esc] characters. (The [Esc] characters can be used to activate ANSI screen functions for line drawings, enhanced characters, etc.) Copy the file to the OMNI4000 directory, then reboot the node, and the new banner will be in effect.
