Int F1

Common ISDN API (CAPI) v2.0 - CAPI_GET_PROFILE - GET CAPABILITIES

AL = F3h
AH = CAPI version number * 10 (14h for v2.0)
ES:BX -> 64-byte buffer for CAPI capabilities (see #04074)
CX = controller number (01h-06h) or 0000h to get number of controllers

Return:
AX = status (0000h,11xxh) (see #04070)
ES:BX buffer filled if successful

Notes: The caller is required to provide at least 512 bytes of stack space
