A method apparatus for selectively passing various types of telephony information between a data communications port on a digital telephone and a computer run application program. In one embodiment, the application program can select a subset of telephony events by way of a telephony command to the telephone's data communication port. This command is processed by a telephony command processor within the data communications controller which, in turn, sets a programmable event mask within the telephone. In response to the event mask being set, only the selected telephony events are spontaneously reported to the host computer and application program.
