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.

Protocols using "promiscuous", "hook" or "chain" mode should always return from the Receive Upcall with the received Mbuf in ES:BX and the Carry Flag set. The DLI will then pass the Mbuf to the FEED BACK BUFFER function (see AX=000Fh).

The receive status passed to the Receive Upcall in register AL is always zero, except for protocols using "non-LLC" mode (8 of PCB's protocol mode field) or "promiscuous" mode together with "receive error frames" (0 & 3). Upcalls are FAR routines and must return with a RET FAR. If the Carry Flag is set on return from a Receive or Transmit Upcall, then ES:BX must point to an Mbuf, which the DLI will then pass to the RELEASE BUFFER function (see AX=0005h).
