Hi,
When Octoprint tries to auto-connect to my device when Octoprint first starts up (say after power on) it sends the command '$$' to the device. I need to be able to stop it from doing this.
After the initial connection drops out (as the $$ is causing an Alarm on my other device because it's not in a state to receive and process the command) then when I press connect it does connect and keep the connection so that I'm then able to continue working with Octoprint.
This the serial chatter showing the first attempt after power on and then the second attempt after pressing the connect button:

Any suggestions would be great, thanks.
