I don't believe this has anything to do with your commits. Thanks for taking time to hunt this issue. I checked the code and sent out a patch to fix the stdio interface if slang lib is not installed. Please see the patch: https://lore.kernel.org/lkml/20220526143917.607928-1-leo.yan@linaro.org/T/#u > Last, it looks like you should update the help text for the display flag options to reflect your new peer option. > Currently it says: > -d, --display > lcl,rmt > > But since you added the "peer" display, shouldn't the output for that help text state: > -d, --display > lcl,rmt,peer Yeah, will fix. Very appreciate for your detailed testing and suggestions.
