Hello everyone,
I've been working on testing PPP support in SLM 2.6.1 without cmux on my Linux host machine. However, I encountered some logs during the process:
Note: For my case /dev/ttyACM2 is assign to different device, so I get /dev/ttyACM3

Given these logs, I'm wondering if there's any dependency on the IPv6 protocol for PPP support in SLM 2.6.1 without cmux. Any insights or suggestions would be greatly appreciated.
Thank you!
