Hello,

I am writing a driver with serial tx/rx.

Great!  For what type of hardware?

I am not sure what is the need console routines, when there is
serial/uart tx/rx.

Isn't writing to console, the same as outputing chars to serial ?

I've tried to find information on this, but found none.

Just follow the "normal" tty api and your driver should be fine and work
with all sorts of consoles and programs and line disciplines.

good luck!
