Hi All, I used vivisimo.com to look for a simple way to create/simulate a high delay environment similar to one that would be experienced via satellite. Unfortunately, I am not adpet at C programming. While there are simulators, most notably http://www.isi.edu/nsnam/ns with a very complete simulation suite, I am trying to find a way to simply instigate a user definable (~600ms +) delay between two working machines. Many Thanks & Very Best Regards Charles
