; Librarian error! I changed James' function name, adding the ft_
; prefix, after testing (error!) and didn't realize that .asm function
; _must_ obey the 10-character limit or the symbol isn't found by the
; linker. Changed the function name to ft_ttsavai() (although calling
; it from Clipper the old way will work). Apologies to all.

; FT_TTSAVAIL()
; $CATEGORY$
; NetWare
; $ONELINER$
; Check whether default Novell file server supports TTS
; $SYNTAX$
; FT_TTSAVAIL() -> nResult
; $ARGUMENTS$
; None
; $RETURNS$
; 0 - TTS unavailable or not supported.
; 1 - TTS is installed and available.
; 253 - TTS is disabled.
; $DESCRIPTION$
; This routine is used to check the default NetWare file server for TTS
; availability. You must have Novell NetWare SFT Level II or above to
; use these functions. Using these functions on a non SFT II file server
; will return unsuccessful values. You must have TTS installed on your
; file server.
;
; This routine was designed and written for Novell Advanced NetWare 2.15
; SFT Level II and Novell NetWare 386 v 3.0 and above.
;
; This source code was written for Microsoft Macro Assembler v5.1.
; $EXAMPLES$
; IF FT_TTSAVAIL() == 1 // If TTS is available
; FT_TTSBEGIN() // Begin transaction
; ENDIF
; $SEEALSO$
; FT_TTSABORT() FT_TTSBEGIN() FT_TTSEND() FT_TTSSTAT()
; $END$
