Circuits.UART.enumerate no work on Ubuntu 20.04

[braulio]

Hello.

Hello
I created a small application to test Circuits.UART. But I cannot enumerate the ports. I use iex -S mix and Circuits.UART.enumerate.

The result is always %{}

Need help.

Thanks.

Could you check that it's possible to use the ports outside of Elixir? Are you a member of the dialout group?

Hello Frank. I managed to send a test message from /dev/pts/2 to /dev/pts/3 after setting permissions with chmod a+rw /dev/pts/2. But Circuits.UART.enumerate still doesn't work. Interactive Elixir (1.12.2) - press Ctrl+C to exit (type h() ENTER for help) iex(1)> Circuits.UART.enumerate %{} I still don't know what's going on. Thank you!

/dev/pts/2 and /dev/pts/3 are not UARTs, so it's expected that Circuits.UART.enumerate won't return them.
