149. xtensions Technical Guide 6 6 Other Common ISUS3 Serial Console Commands Before detailing other common console commands for the ISUS there is one thing that should be noted about method The ISUS console as you will notice when connected is fairly busy at times outputting the card status as various functions are enacted This output stream is separate to any input you make except for the responses to your input When you are typing in commands you cannot be sure the display of the string you are entering will not be interrupted by an on screen status output The effect of any such interruption is that you may have the impression that your input is lost it is not as noted the in and out streams are separate So when entering a command you primarily need to ignore any status outputs and just keep typing your command string If you get a command spelling wrong the card will tell you with Unrecognised or other so you should look at the screen immediately after you send the command with your Enter key Otherwise if you are really unsure about the entry of an IP or other number then you can enter the command and details again Factory Default If for any reason eg perceived corruption you wish to factory default a VIU ISU3 card issue the command ggdbg set default factory Enter The card will then reboot loading the factory defaults in the process Note all settings you have made will be lost so these need to have been noted
