Accessing serial port from kernel space

Accessing serial port from kernel space

[Tcendrovskii Vladislav]

Hello!

I need to access serial port from my module. But I haven't found
functions to access it. And as i understood, all work with serial port
goes through TTY system.

So, if it exist some documentation on this system, and how can i use it
from kernel space? In tty.txt i've found only line discipline, which is
not, what i need.
