SSH Connection to a Biamp TesiraForte AI mixer

in AMX Technical Discussion

I spent a bunch of time writing the code necessary to talk to our first Biamp mixer. This was also my first foray into SSH connections. Please feel free to use my code; it is a thank you for all of the valuable information I have gleaned from this forum.

    I will post the data event in two chunks, or complete, once I figure out how to post a large code snippet.

    I did not do anything with ONERROR, as I have not yet had problems.
    The data event checks for and parses all the suggested possible negotiation strings, as documented in the Biamp Tesira Text Protocol manual.
    I hope this saves someone some time. This forum has saved me a considerable amount of time over the years. Thank you.

    Nice! Thanks for posting. The detailed documentation on session negotiation is particularly sweet. :)

    If anyone is willing to share the trick of getting this forum to show space/tab indents in code posts, it would be appreciated. Thanks.

  • zasadatzasadat Posts: 25

    I would happily upload an AXS file with my code snippets, or post with a best practice. Can't find the help files for this forum. Some stuff is just too darn technical. Sigh.

    No, that can't be right... according to the footnote it's made with <3 . Clearly, you're wrong... :D

    I am curious why the sMixerBuffer is Non Volatile?
  • zasadatzasadat Posts: 25

    After reviewing the variable keywords in the Netlinx manual, it appears as though I declared the buffer as NONVOLATILE mistakenly. I do indeed wish to have the buffer cleared at power-down or reload. Thanks for bringing this to my attention, JasonS.
