All, I got up this AM to a nice collection of responses and information. Thanks to all.
Glenn, thanks for the Tek Scope article. Hal, I think that is the command I remember. I was searching under Z3816A, not Z3801A. I'll give it a try. Perhaps I was not clear about 'soap'. What I was planning was dish detergent. I can choose either regular dish detergent or dish washer detergent. Any preference? These are not the same. Any guess as to how I know this? I'll report back after further effort. Now, off to work. Thanks again.
