Hi Paul,
I see what you mean regarding interleaving the command's echo with the
reply. I should add that I dropped the baud rate from 9600 to 1200 on
the Fluke 45 in a bid for better results. It didn't occur to me that
that my exacerbate the problem when echo was turned on on the Fluke 45
until reading your comment.

We see here echo intermixed with the reply to the previous FUNC1?
command. So it's "AUT" from the echo, "VDC" from the real reply to the
previous command (FUNC1?), and "O?" from echo, then "1" and then "\n"
likely from echo again. Of course, it's all timing-dependent but it's
essential to know the echo works essentially in parallel to answering
the previous request.
