When I specified stty isig, the following error occurred. I found a similar problem but did not resolve it. I searched for a lot of information but I'm not sure what's going on. I have no clue, can anyone help me? I am using Busybox's own stty.
# tty
/dev/tty1
stty isig

stty -ato your question ? If Busybox is acting as your shell, it may need to prevent you from changing how it handles signals. – Paul_Pedant Feb 01 '24 at 09:54isig.
