-Inheritance is one of the great features of object oriented languages like C++. The stream methods are not included in serial to allow you to use them in other classes as well. They are for example also included in the TextLCD class and in my enhanced TextLCD class. All you need to do to make use of the powerful printf features is implement a putc() method in your own new class.

+Please note, this is all 'beerware' code but I would appreciate a mention in your code headers
+if you use some/all of my code/classes. My name is Johan Kritzinger and I go by 'JoKer' on MBED.
+My C++ is not that hot (I'm an old PLM-51 and C programmer) but the only way to learn is to do.
+Any questions, please feel free to ask.
