I know, that there are some standards in tty naming.

There is ttyUSBx for USB to serial converters, ttySx for RS-232, ttyAMAx on ARM devices, but I can't find anything about conventions in RS-485 port naming.

I'm preparing linux distribution for custom ARM-based machine and I want to name things properly.

The question is: are there any conventions in tty device naming for RS-485 serial ports?

    As far as I can tell, it looks like the convention might be the same (ttySx) for serial devices. That being said, it would be relatively easy to create a udev rule (or rules) that use a more intuitive naming convention. – Caleb Reister Nov 24 '18 at 20:29
