A communication device includes at least two output apparatuses, and an interface circuit configured as an interface between the at least two output apparatuses and software drivers supported by an operating system embedded within the communication device, so that the software drivers can access the output apparatuses. The interface circuit includes an access control circuit configured to temporarily allocate a first one of the at least two apparatuses with a first one of the software drivers, so that other ones of the software drivers cannot access the first output apparatus during its allocation to the first software driver. The interface circuit also includes shared resource circuits configured to dynamically direct communication from the first software driver to the temporarily allocated first output apparatus.
