INT 2F - NETWORK REDIRECTOR - CREATE/TRUNCATE REMOTE FILE

	AX = 1117h
	ES:DI -> uninitialized SFT
	SS = DOS DS
	SDA first filename pointer -> fully-qualified name of file to open
	SDA CDS pointer -> current directory structure for drive with file
	STACK: WORD file creation mode
			low byte = file attributes (see #01401 at INT 21/AH=3Ch)
			high byte = 00h normal create, 01h create new file
Return: CF set on error
	    AX = DOS error code (see #01680 at INT 21/AH=59h/BX=0000h)
	CF clear if successful
	    SFT filled (except handle count, which DOS manages itself)
	STACK unchanged
