Looking closely, it seems it's due to a spurious ^M in the output: C ^[[35C^[[42D^M ^[[0m^@^@English^[[35C^[[42D^[[A^@^@C which goes to the beginning of the line. Without screen, the sequence is: C ^[[35C^[[15;35H^[[m^OEnglish^[[35C^[[14;35HC i.e. it uses absolute coordinates, and thus no issue. I wonder where this ^M comes from.

Probably not, I usually find on the Internet that serial console = vt100/vt102 Samuel
