¿There is an example of a working example of serial port on ROS Indigo and C++?

edit

I'm working with ROS Indigo and Ubuntu 14.05, and I've found a serial library from William Woodall and John Harrison ( https://github.com/wjwwood/serial/ ) that seem to be exactly what I want. They say that is compatible with ROS, but I'm not finding the way to make it work. A working example with a "hello world" on serial port will be enough for me, because I think my problem is with the dependencies on the CMakeLists.txt.

PD: By now I'm able to compile and run the "serial_example.cpp" included on the package, but that doesn't use ROS, I've tried to make it work but i don't know where's my error.
