AT commands

[Normand Roy]

I need to monitor modem temperature on modems running in a production environment. So running it in debug mode is not an option.

I will make a suggestion to the modem manufacturer to implement a plug-in for MM. I won't be able to do this by myself.

Thank you for your help.

That all said, obviously sometimes random AT commands are needed for reasons like this, and for debugging.  But they are allowed under the "debug" mode specifically because they aren't officially supported, and if something breaks now or in the future, you get to keep both pieces.
