Ok,  this  is  just  a  rough doc about the onlineport of HDOff.  Sorry for
this.  To use this, you should be used to MsgPorts and their handling!

The port`s name is : HDOFF_PORT

The port`s structure is:

	STRUCTURE       HD,MN_SIZE
		UBYTE   HD_Cmd
		WORD    HD_TimeHD0      ;Time in secs (startvalue)
		WORD    HD_TimeHD1
		WORD    HD_TimeLeftHD0  ;Time in secs (actual)
		WORD    HD_TimeLeftHD1
		UBYTE   HD_StatHD0      ;$ff: Drive off
		UBYTE   HD_StatHD1
		ULONG	HD_PortVer	;Version of the port
		LABEL   HD_SIZE

The actual portversion is: $100  (standing for 1.00)

Here are the commands:

hd_GetStats     equ     $00
~~~~~~~~~~~
This gives you back the filled structure.

hd_SetStats     equ     $01
~~~~~~~~~~~
You  can  set  HD_TimeHD0 and HD_TimeHD1 to new values, and you will get an
answer like hd_GetStats.

hd_Subscribe    equ     $02
~~~~~~~~~~~~
If  you  subscribe,  you  will  get  a  message  everytime a drive has been
switched  on/off.   Check  the  answer!   If  HD_Cmd=0 your subscribing was
unsuccessfull.

If  a drive changed its status, you`ll get a messy with HD_Cmd=hd_Subscribe
filled with the new data`s.  You must not change/reply or do something else
with this messy (except reading it out, of course ;) !

hd_Unsubscribe  equ     $03
~~~~~~~~~~~~~~
You  won`t get a messys on a drive power down/up any more.  If HD_Cmd=0 you
weren`t subscribed :)

hd_StopDrive    equ     $04
~~~~~~~~~~~~
Here you can switch a drive off by setting HD_StatHDx=$ff.

hd_Quit         equ     $05
~~~~~~~
This tries to terminate HDOff.  If the reply has HD_Cmd=hd_Die quitting was
successfull, if not not :)

hd_ForceQuit    equ     $06
~~~~~~~~~~~~
The same as hd_Quit, but using the force option (can`t fail), and you won`t
get a reply.  NOTE:  read the warning about the FORCE-option in the doc!

hd_Die          equ     $FF
~~~~~~
NOTE:  you can _only_ recive this!  If you get this Message, HDOff has been
terminated and you must stop using the port any longer!

Ok, I hope every clarity has been removed ;-)

BTW,  does  anybody want to code a nice GUI for HDOff?  Like a commodity or
something.  If you do, please contact me!!
