INT 7C - SK-UPPS Data Link Interface API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running. Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes. - 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.
