How to avoid "ATE1 E0" sequence

[Gregoire Gentil]

Hello,

Each time I use minicom to my embedded device, I get the following:

OPTIONS: I18n
Compiled on Aug 13 2017, 15:25:34.
Port /dev/ttyACM0, 12:02:43

Press CTRL-A Z for help on special keys



Login incorrect
inout login: ATE1 E0
Password:


How can I avoid that Minicom sends the modem command? I have tried to 
disabled/put to zero everything in the modem setting screen - but no change,
