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. InstallCheck: test for the ASCII signature string "UPPS_DLI" immediately preceding the interrupt handler Notes: 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. SeeAlso: AX=0000h,AX=0002h,AX=000Fh Index: installation check;SK-UPPSTop

INT 7C - SK-UPPS Data Link Interface API - CHANGE DRIVER ADDRESS AX = 0003h ES:DI -> new node address (6 bytes) Return: AX = completion code (see #03846) Note: the DLI will refuse to change the address if any protocols (see AX=0007h) are active SeeAlso: AX=0001h,AX=000EhTop
INT 7C - SK-UPPS Data Link Interface API - REQUEST BUFFER AX = 0004h DX = protocol ID (see AX=0007h,#03849) Return: AX = completion code (see also #03846) 0000h successful ES:BX -> Memory Buffer (Mbuf) (see #03847) Note: if the DLI has no free Mbufs, it will set an internal flag for the protocol and later call the protocol's Event Upcall with EV_BUFFER_AVAILABLE (see #03853,#03854) as soon as an Mbuf becomes available. There will only be one "buffer available" Upcall, even if this function has been called several times before. SeeAlso: AX=0005h,AX=0006h,AX=0012h,AX=0013h Format of SK-UPPS Memory Buffer (Mbuf): Offset Size Description (Table 03847) 00h DWORD -> NEXT Mbuf (linked list) 04h WORD OFFSET of actual data within DATA area 06h 2 BYTEs reserved (currently unused) 08h WORD LENGTH of actual data found in DATA area starting at OFFSET 0Ah 2 BYTEs reserved (currently unused) 0Ch DWORD -> DATA area (size can be obtained via AX=000Eh call) 10h WORD PROTOCOL ID of protocol currently "owning" the Mbuf 12h BYTE IN USE flag; nonzero if Mbuf still in use by DLI (see AX=0006h) 13h BYTE RECEIVE STATUS (bit 0-7 only; see AX=0007h - Receive Upcall)Top
INT 7C - SK-UPPS Data Link Interface API - RELEASE BUFFER AX = 0005h ES:BX -> Mbuf (see #03847) Return: nothing SeeAlso: AX=0004hTop
INT 7C - SK-UPPS Data Link Interface API - TRANSMIT FRAME AX = 0006h ES:BX -> Mbuf (see #03847) Return: nothing Notes: The DLI will send LENGTH bytes found in the Mbuf's DATA area starting at OFFSET. A complete and valid frame must be stored there. The DLI will only copy the current node address (see AX=0003h) to the source node field of the frame's MAC header. On Ethernet, the DLI will always send a minimum of 60 bytes, regardless of the value found in the LENGTH field. This function returns immediately; the DLI will call the protocol's Transmit Upcall (see #03848) when the frame has been sent. The Mbuf's IN USE field will be non-zero until the DLI calls the Transmit Upcall. SeeAlso: AX=0002h,AX=0004h,AX=0013h (Table 03848) Values SK-UPPS Transmit Upcall is called with: ES:BX -> Mbuf (NEXT field destroyed) interrupts disabled Note: On FDDI the bytes of the source and destination node fields in the MAC header have been bit-swapped to physical address format.Top
INT 7C - SK-UPPS Data Link Interface API - REGISTER PROTOCOL AX = 0007h ES:BX -> Protocol Control Block (see #03849) Return: AX = completion code (see #03846) Program: SK-UPPS is the Schneider & Koch Universal Portable Protocol Stack, which provides an API on top of its Data Link Interface, allowing the use of any of several network transport layers SeeAlso: AX=0008h,AX=000Bh Format of SK-UPPS Protocol Control Block (PCB): Offset Size Description (Table 03849) 00h WORD (big-endian) protocol type 02h WORD protocol mode (see #03850) 04h DWORD -> Receive Upcall routine (see #03851) 08h DWORD -> Transmit Upcall routine 0Ch DWORD -> Event Upcall routine (see #03853) 10h DWORD -> ASCIZ protocol name (zero if none) 14h WORD protocol ID will be returned here (always non-zero) Bitfields for SK-UPPS protocol mode: Bit(s) Description (Table 03850) 0 promiscuous mode; protocol receives all frames regardless of their destination (PROTOCOL TYPE must be FFFFh) 1 if set, protocol's Event Upcall will be called on entry and exit of the DLI's Interrupt Service Routine (see #03854) 2 DLI 2.2+ hook mode; protocol receives all directed frames destined for this station (PROTOCOL TYPE must be FFFFh) 3 DLI 2.3+ receive error frames (only valid in promiscuous mode (0)) 4-5 DLI 2.5+ frame type: 00 Ethernet II; specify type code in PROTOCOL TYPE field (high-low) 01 IEEE 802.2; specify Service Access Point (SAP) in MSB (offset 0) of PROCOTOL TYPE field; LSB must be zero 10 IEEE 802.2 with SNAP header; specify type code in PROTOCOL TYPE field (high-low) 11 reserved (currently unused) 6 DLI 2.5+ if set, protocol's Event Upcall will be called with event code EV_BUFFER_WANTED, when DLI runs out of Mbufs 7 DLI 2.7+ chain mode; if set, client allows the specified frame type to be shared with other clients 8 DLI 2.8+ receive non-LLC frames rather than LLC frames 9 DLI 2.8+ receive all multicast frames (see also AX=0009h) 10-15 reserved (currently unused; must be zero) Notes: If PROTOCOL TYPE is FFFFh and neither the "promiscuous" nor the "hook" mode is set, the protocol receives all frames that did not match any registered frame type (demultiplexor mode). 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. SeeAlso: #03849 (Table 03851) Values SK-UPPS Receive Upcall is called with: ES:BX -> Mbuf AX = receive status (see #03852) (also stored in Mbuf's RECEIVE STATUS field) interrupts disabled Return: nothing SeeAlso: #03853 Bitfields for SK-UPPS receive status: Bit(s) Description (Table 03852) 0-2 reserved (0), currently unused 3 frame check sequence (FCS) error 4 overflow (frame too long) 5 framing error 6 reserved (0), currently unused 7 non-LLC frame (see #03850 [bit 8]) 8-15 reserved (0), currently unused Notes: The protocol's Receive Upcall routine will be called whenever a frame matching the specified frame type is received. 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). See also notes for PROTOCOL MODE. (Table 03853) Values SK-UPPS Event Upcall is called with: AX = event code (see #03854) Return: nothing Note: All Event Upcalls may be ignored by the protocol.

INT 7C - SK-UPPS Data Link Interface API - DISABLE PROTOCOL AX = 0008h BX = protocol ID (see #03849) Return: AX = completion code (see #03846) Note: the DLI will handle any Mbufs given to TRANSMIT FRAME (AX=0006h) as if they had been given to TRANSMIT FRAME RELEASE (AX=0013h). all multicast addresses registered for this protocol will be disabled. after this function returns, the protocol's Upcall routines will no longer be called.
