INT 60 - Excelan LAN Workplace for DOS 3.5 - 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.
ES:BX -> request packet (see #03272)
Return: request packet updated
InstallCheck: test for the WORD 4142h ('AB') immediately preceding the
interrupt handler
Note: this interrupt is also supported by Beame&Whiteside's BWLWP35 shim,
which was used in creating this description
BUG: because BWLWP35 range-checks only the low byte of the function number,
and has a fencepost error even in that test, functions 000Bh and
XX01h-XX0Bh (XX nonzero) branch to random locations
