Chris -
I don't doubt what you're saying at all, but you might want to direct your
statement to Denny since he's the one with the issue.
The ability to do what you describe with the 64-port terminal server is
very, very, cool. What you're alluding to is referred to as a "reverse LAT"
in "DEC-ese," but I'm sure you're not using DECnet to accomplish it.
