Hello,
I have the problem that in the serial console and the SSH shell escape
sequences are displayed instead of colors.
This is not nice, but much worse is that I have to end every command like
“nmcli con show” with “q” to get back into the shell.
Similar to if I had started it with “| less”. See the screenshot in the appendix
However, if I start the command with “NO_COLOR=true nmcli con show”, the output
appears correctly without the “less mode”.
I have already tried various terminal settings in the SSH client.
But I think the problem is in the Yocto image itself, and not on the client
side.
The environment variable TERM is set to “xterm”. But I also tried
“xterm-color”, which did not change anything.
Does anyone have an idea what the problem could be, or what I could look for?
I assume you are running busybox?
We had the same issue and fixed it by adding this patch to busybox:
https://git.embedded.cherry.de/yocto-layers/meta-cherry-es.git/tree/meta-extended/recipes-core/busybox/busybox/less_raw.cfg
Does that work for you?
I unfortunately didn't take the time to look into how to contribute this
to OE-Core so other people benefit from it. I assumed we may not want to
have it always enabled but maybe that's fine. I thought maybe we want
this behind a DISTRO_FEATURES such as NO_COLOR but haven't really put
much effort in looking for a solution.
Cheers,
Quentin
