INT 7C - SK-UPPS/SK-PASSPORT Data Link Interface (DLI) API
Program: SK-UPPS is the Schneider & Koch Universal Portable Protocol Stack,
          which provides an API on top of it Data Link Interface, allowing the
          use of any of several network transport layers; this product is
          called SK-PASSPORT in the USA.
Notes:  The installation check consists of testing for the ASCII signature
          string "UPPS_DLI" immediately preceding the interrupt handler.
        To find the service interrupt being used by the driver, an application
          should scan through the interrupt table until it finds an interrupt
          vector with the "UPPS_DLI" string.
        There may be more than one DLI loaded, each having its own service
          interrupt.
