[CommunicationAPI] RS485 stopped when there's printk or console interaction through usb

[Rodgeur31]

This is a first draft of the issue description.

When we want to use RS485 in communcationAPI with Twist boards, the communication seems been corrupted and stopped when there's communication with the console through the usb port.

But when we use STLink and lpuart port there's no problem.

I will update these part later...to have a reproducible example.
