Just in case it helps anyone else, tio (https://github.com/tio/tio) is a great featureful alternative to picocom.

You can use snap or brew or build from source?

The 841N works with OpenWRT. But AFAIR pretty much an EOL device with not much flash/ram.

the idea is more to get into hardware hacking.. the hardware is kind of irrelevant ... the most important thing is a sane UART exposed, documentation, videos about it and etc..

I had one of those sitting in a drawer for years. I think i did get OpenWRT on it at one point. Eventually it just stopped working altogether, but i felt like i got more than my money's worth out of it. Even brand new that router cost next to nothing.

Funny enough i have the same multimeter too

Clearly the problem is the firmware was not written in Rust. I suggest a Rust rewrite so that these sort of errors will go away.
