Prioritizing resources between the configmenu and serial ports on the CM.

If for example you have many ports constantly spewing data you may notice slowdown when using the CLI configmenu.  You can prioritize resources between the configmenu and ports by following these steps.

To change the priority of the CLI menu (configmenu) and ports (vts.cport) program, create the following files:
          configmenu  => /usr2/menupriority  
          vts.cport => /usr2/portpriority
 Each file should contain an integer value between -20 and 19 ( -20 is the highest priority and 19 is the lowest priority).  You will have to test and see what works best for you. 

To set this permanently:
 --Edit /usr2/rc.user and add these lines above “exit 0”
  cp –a /usr2/menupriority /etc
  cp –a /usr2/portpriority /etc
 
--reboot
