	AX = 8221h
Return: AX = status
	    5722h successful

	BX = BCD(Binary Coded Decimal) A method of data storage where two decimal digits are stored in each byte, one in the upper four bits and the other in the lower four bits.  Since only the values 0 through 9 are used in each half of a byte, BCD values can be read as decimal numbers on a hexadecimal display of memory or a file. version number (BH = major, BL = minor)

Format of Output Device structure [array]:
Offset	Size	Description	(Table 02961)
 00h 20 BYTEs	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. name of the output device
		(end of list if first char is FFh)
 14h	WORD	apparently always FFFFh
 16h	WORD	0000h if output device not available
		else first I/O port for the output device
 18h	WORD	second I/O port for the output device (for example
		  if it is stereo)
		000oh if only one port used or device is not available
 1Ah  7 BYTEs	???
