You mean in barebox, or in the host where I'm running minicom/microcom?

Interesting. I tried that, the result is:

- Still the same problem when scrolling up and down in "edit" (A and B
characters inserted)
- Many more missing chars when pasting "Lorem ipsum.." (_in "edit"_).
Here are three examples:

Loe Ismismyuye   iinatestis.
Loe Ismismyuye  eiinatest uy.
Loe Ismismyuye   iinatest uy.

- The very same text can be pasted perfectly in barebox's command
line, no missing chars. The problem is only with the "edit" command.
What makes "edit" different ?
