INT 60 - AccessDOS - 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 = ADh AL = function E1h ??? Return: AX = ??? E2h get configuration Return: BX:AX -> configuration data Program: AccessDOS is a public domain 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. developed at The Trace Research and Development Center which provides extensions for keyboard, mouse, and sound access by the visually, hearing, or motor-control impaired. InstallCheck: test for the signature "ACCESSv1.00" beginning three bytes past the start of the interrupt handler (this same signature is also present in v1.10) Range: INT 60 to INT 66, selected by scanning for 0000h:0000h vector
