  • Method and system for IP address accessibility to server applications
    Patent number: 6216159
    Abstract: A Telnet server makes the IP address of a Telnet client accessible to applications by writing the IP address into device associated space initialized when the virtual device at the server is associated with the physical device at the client. Applications retrieve this device IP address using an API, and are thus enabled to do job routing, printer passthru, access control and so forth using TCP/IP networks.
