Format of Telebit ACS parameter block:
Offset	Size	Description	(Table 03867)
 00h	BYTE	command (see #03868)
 01h	BYTE	gateway number
 02h	BYTE	reserved
 03h	BYTE	port
 04h 17 BYTEs	auxiliary buffer
 15h	BYTE	session
 16h	WORD	count of bytes passed to 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.
 18h	DWORDDoubleword; four bytes.	 Commonly used to hold a 32-bit segment:offset or selector:offset address.	buffer pointer passed to/from 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.
 1Ch	WORD	count of bytes passed from 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.
 1Eh	BYTE	return code (see #03869)
