It is available from the RMCEMC website at http://www.ieee.org/rmcemc Navigate to the archives and use the search engine to locate the file. Enjoy.

I'm a newcomer as well(just got finished testing out my Very First multigigabit card, and it works!!!) and would like to just reinforce that there are people interested in the answers to the questions this list poses. So, whenver possible, please answer to the list, not just the person asking the question. Scott and Mick, could you post these answers to the list or include my address when you answer? Thanks, Tegan -----Original Message----- From: Ben Rothchild [mailto:benrothchild@xxxxxxxxx] Sent: Friday, February 15, 2002 5:06 AM To: xlzhou@xxxxxxxxx Cc: si-list@xxxxxxxxxxxxx Subject: [SI-LIST] Re: Diff line Hi Mick, Can you explain what you mean by modes and how they affect.
