Adding a configuration entry to the terminal settings may resolve the issue.
Navigate to Scout Console:
Access Advanced device configuration:
Add the following entry:
/setup/terminal.iniKeyboardForceShiftLocktrue

Restart the device(s):
The Caps Lock key may not function correctly when entering special characters, even in applications like xterm or the file manager.
If the Caps Lock key does not work for entering special characters, adding the ForceShiftLock=true entry in the /setup/terminal.ini file under the Keyboard section should resolve the issue. Use Scout Console to apply the configuration and restart the device(s).
