Hi,

Maybe if it comes to "initializing the sources..." - downloading several files withs lots of Progress screens - then it sends quite of lot of screen changes per second. Maybe I'm wrong but this is my feeling from how I understand Roberto's question.

Yes. They are asking if there's a way to limit/reduce/elliminate all that output. Let me explain why? Their systems are multi-node systems. So they could be upgrading anywhere from 8-300 nodes simultaneously. So no one is going to be looking at these installs. And to make matters worse, some of their customers only allow say 20/30 minutes to upgrade a node because their core critical business is dependent on these nodes running customer product. So anyway to reduce that upgrade time is a plus and oh BTW, they know that turning off the SOL connection decreases the install time, but like I said this is a requirement. -robert
