INT 16 - CtrlAlt Associates STACKEY.COM v3.00 - 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. AH = CAh BX = 736Bh ("sk") CX = 736Bh AL = function 00h installation check Return: DX = words available in keyboard buffer 01h place keystroke in buffer DX = keystroke (DH = scan code, DL = ASCII character) Return: DX = words available in keyboard buffer FFFFh on error 02h flush STACKEY and BIOS(Basic Input/Output System) A set of standardized calls giving low-level access to the hardware. The BIOS is the lowest software layer above the actual hardware and serves to insulate programs (and operating systems) which use it from the details of accessing the hardware directly. keyboard buffers Return: AX = CAFFh if installed BX = segment of resident code CX = STACKEY version (CH = major, CL = minor) Program: STACKEY is a shareware keyboard-input faking TSR(Terminate and Stay Resident) A program which remains in memory after terminating in order to provide services to other programs or the user. The name comes from the name of the DOS function call used to remain in memory after termination. Index: installation check;STACKEY
