First, the FreeRTOS (as a kernel) has no I/O functions, the only interrupt it handles is the timer, and in some ports a Software interrupt for the task switch. There are some examples of I/O routines in the demos, but technically those are not part of the OS, You can probably find a simple UART implementation in the demos that you can copy to your project.
