Seems like the most interesting part is part of this file:

# cat /tmp/fileVotmuV
libgpm: zero screen dimension, assuming 80x25.

the temp file is created by the script
class/40-parse-profiles.sh

I've ask a friend that have suggested to remove the 1>$out at line 150
and 161.
Now, I can press enter in the menu and it's working over the serial
console and also on the normal screen.

But, I've lost the capacity to navigate the menu, it ouputs garbage instead.

Let see...
