  • Remote processing of a plurality of commands during a session between a first computer and a host computer
    Patent number: 5375207
    Abstract: In a computer system having a host computer connected to one or more personal computers, a data transport system sends data back and forth between the host computer and the personal computers. Individual applications on a personal computer utilize resources on the host computer by use of a requester process existing on the personal computer. The requester process translates or reformats commands and associated information for sending to the host computer. A host server oversees the execution of such commands received by the host computer, and may call database intrinsics, operating system intrinsics, or remote procedure intrinsics to obtain execution of the command.
