Implement custom open method for HW OSTC 3 family

Browse Source 
Create a custom open method for HW OSTC3 family.
This method can be used to pass a reference to a dc_serial_t
structure. In this way the applications can implement their
own implementation for a serial communication and set their
callbacks for the basic serial functions.
