SSH Connection to a Biamp TesiraForte AI mixer

Posts: 25
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 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.
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
. Clearly, you're wrong... 
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.
This should be easier to read.
