Can i use of am335x user uart without /dev/tty*?

I am using BeagleboneBlack which has am335x processor and me curious to know about user uart working with /dev/tty node so my question is "Can I use user uart without using /dev/tty entry? or another node entry? or can I make a custom uart kernel module with a different node entry (not use dev/tty)?"

I know this is weird things but this question is for only knowledge

Yes. You can. There are libraries that handle UART but just call the UART by another name, i.e. UART1, 2, 3, 4, 5 (etc).

I have found some libs that work like Adafruit_BBIO and pysabertooth. The pysabertooth lib works with the BBB and dimension engineering boards like the Sabertooth.

I mean literally, you can in a lib call the UART channels anything you wish. I see the answer the other fellow put down. I am currently not familiar w/ serdev. That may be an option but I am not skilled in uart/serdev in kernel 4.11.x.
