I had things setup so one J6 went to ntpd and the other went to a hack that logged some data and displayed an occasional status screen. Then I had a power failure. One side came back OK. The other was sending some junk every second and ignoring what I sent to it. I found an old message that covered part of the problem. https://www.febo.com/pipermail/time-nuts/2014-November/088446.html I can now talk to it and it does what I expect. Except that I don't get any "scpi> " prompt to tell me when it is ready. I tried resetting to factory defaults. Is there another command that I'm missing? -- These are my opinions. I hate spam.
