Hi Nicholas,

Thanks for your time in testing this.

Just to be sure:
Can you confirm you've used the latest master and applied my patch 
before seeing this error?

I'm not able to simulate your error here currently, and the script 
manages to adapt this flag on each run.


Besides the error you notice, is your modem fully working now providing 
a working uplink?


Thanks again,

Koen
