As starting guide:

Serial HOWTO
http://tldp.org/HOWTO/Serial-HOWTO.html

Serial Programming HOWTO
http://tldp.org/HOWTO/Serial-Program...WTO/index.html

A 'man -k serial' might provide additional info. Checking
Documentation/serial (inside a Linux kernel tarball) has although
info.

Good luck

Chances are that no, you don't. A kernel level library to communicate
with the serial port is called a "driver". Unless you are working with
some exotic board that has a strange new UART chip, your kernel has
that driver already.

So in other words ``that'' was not kernel-level programming. You were
calling Win32 functions in a DLL from the Windows equivalent of user
space.

open and read: functions as old as Unix itself. Good grief!

As others have pointed out, you probably
don't want a "kernel level" library. That
would be a driver.

If you truly must use a UART from kernel
space (inside a device driver), look up
line discipline drivers.
