The task expects "LOWERCASE" and this is exactly what's read from the node, but for some reason the text contains some ANSI characters (actually bracket paste mode). Therefore the line contains "LOWERCASE" but doesn't match the exact result.
This issue was reproduced only on Arch Linux machines, Ubuntu machines don't seem to have any issues. I also tried different versions of python and still get the same issue.

Steps to reproduce the issue
Run e.g BOARD=samr21-xpro make -C tests/test_tools flash test.
Expected results
The test should pass
Actual results
As described above, the test fails.
