Abstract: A communication interface for providing asynchronous and telephonic communications is disclosed. The interface enables software applications, which are independent of any hardware or physical addresses, to operate on the interface. In this manner, the software applications can be written independent of hardware implementation and protocol implementation. A set of configuration parameters is defined for both an asynchronous and telephonic communication function set. Additionally, a set of interrupt conditions is defined for both the asynchronous and telephonic communication function sets. These parameters and interrupt conditions control the interaction of the software applications across the interface with the system hardware. Means are provided for directing commands coming from a software application across the interface to the system hardware. Likewise, means are provided for generating interrupts and handling these interrupts from the system hardware across the interface back to an interrupt routine within the software application.
