Starting guide for what? Programming in C, programming on Linux, or writing device interface code?? We don't know what you are familiar with, so it's hard to say. There are plenty of C programming tutorials out on the web, so I am assuming you mean for device-interfacing.
From a quick Google search:
A C program tutorial for a serial port test program.
