REMOTE SERVICES CONSOLE FOR DIGITAL DATA PROCESSING SYSTEM

摘要

83-392 A remote services console for transferring communications data among a console port and communications port of a digital data processing system, the system console and a remote services center which provides remote maintenance and diagnostic services. The remote services console operates in three operating modes. In one mode, communications data is transmitted directly between the communications port and the remote services center and between the console port and the console terminal. In a second operating mode, communications data is transmitted between the console port and the remote services center through a microprocessor, the microprocessor being able to insert protocol data into the communications data transmitted to the remote services center and stripping the protocol data from the communications data received from the remote services center. The protocol data serves to ensure proper transmission of communications data to and from the remote services center. Under some circumstances the communications data may be copied to the console terminal, and the console terminal may transmit communications data to the remote services center through the microprocessor. In a 83-392 third operating mode, communications are effected between the communications port and the remote services center through the microprocessor.
