A programming interface to connect devices together for an adapter card that supports multiple devices and I/O ports is described. The interface provided can be supported by a variety of different cards and devices. Each card in the family provides at least one I/O port. Each card in the family also allows one or more of the following devices to be connected - Telephone or speaker phone - Telephone lines - Speaker - Microphone - Headset (speaker + microphone) It is assumed that, if an adapter card supports a telephone and a telephone line, the initial and default connection state is for the telephone to be connected to the telephone line for manual operation. This implies that whenever both devices are free, that is, one is not in use by an application, the Programming Interface will connect them together.
