6F corresponds to IRQ23 on the original HP Vectra AT, which is unavailable because of its use as a BIOS extension software interrupt the INT 6F handler consists of an instruction to load DS with the driver's data segment followed by an indexed far jump using BP to select the destination vector; since the interrupt handler is located immediately following the dispatch table, the HP_VECTOR_TABLE may be found by looking at offset 0000h in the INT 6F segment, and its size is equal to the offset of the interrupt handler each entry in the HP_VECTOR table consists of a DWORD for the driver's entry point address and a WORD for the driver's data segment this function is not user-callable, as it is a response to a physical event, and assumes that the caller has already handled the physical

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). Some DLIs do not support all or even any of the "promiscuous", "receive non-LLC" and "receive all multicasts" mode bits.

A received frame is passed to the protocol in the Mbuf's DATA area at OFFSET and its size is LENGTH bytes. 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).
