Are you trying to write your own device driver for a serial port? Or
are you just trying to write a C (or whatever) program that uses a
serial port?
Unless you are doing the first of those, you don't ever touch interrupts
on any Unix-like system. Any "real OS" will provide you with services for
using serial communications devices, and LInux certainly falls into that
category.
You open a serial port just like it was a file (which it is), set the
parameters (speed, parity, etc.) with ioctl() calls, then read()/write(),
and when you're done use close(), just like a file.
I suggest you look for the Linux Serial Programming HOWTO (that name is
from memory, it may be slightly different) for all the gory details.
