General discussion • Re: uart serial port cannot be detected by minicom

Have you tried using /dev/serial0?

According to https://www.raspberrypi.com/documentati ... imary-uart it is the primary UART alias and will be the same regardless of whether you are using the minUART or the PL011

although python serial tools list_ports and miniterm still cannot find /dev/serial0, minicom can connect /dev/serial0, and can receive data from scanner. . Then test with python serial code, it can read the data from /dev/serial0.

By the way, I test Raspberry Pi 3 with same scanner, both /dev/ttyS0 and /dev/serial0 work in minicom. Raspberry Pi Zero W, only /dev/serial0 works.

Thanks for all of your help! You save my day.
