Until you replied to my post, I'd never thought to check. When I was troubleshooting my issue today, I did look for it in access2 programming, but could only find the NAM sn.
I suspect you might find it with a laptop hooked up, but I resolved my problem before I got that far, and couldn't justify billing the customer overtime to keep looking.
The next time I'm working on a NAM, I'll find an excuse to look for it. I'd like to know, too.
Thanks again for your help.
