INT 17 - Alloy NTNX, MW386 - SPOOL(Simultaneous Peripheral Operation OnLine)  The process of performing output to a slow peripheral such as a printer while other tasks continue running on the CPU.  This term dates back to mainframe days before the invention of timesharing. FILE BY NAME
	AH = 90h
	AL = mode
	    00h NTNX compatibility
		DL = printer code (FFh=current) (NTNX, MW386 v1.x only)
		DH = number of copies (FFh=current) (NTNX, MW386 v1.x only)
	    02h MW386 v2+
		BX = logical device number
		    00h-03h = LPT1-LPT4
		    04h-07h = COM1-COM4
	CX:SI -> ASCIZA NUL-terminated ASCII string.	The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h.  Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL. pathname
Return: AL = status (see #00642)
Note:	in mode 00h, the file is always sent to logical LPT1
