Abstract
A method and apparatus for detecting and recovering from call waiting interference to data communications is disclosed. In a system wherein a first party communicates with a second party via a telecommunications link, the telecommunications link may be disrupted by a third party's attempt to call the first or second party. The present invention detects such a disturbance on the telecommunications line and allows the first or second party to answer the call from the third party. The invention re-establishes communications after the call with the third party is completed.
