Alerting Sounds at the HHT			2 Feb 01

    The HHT Control System now makes distinctive noises to get your attention.
Four kinds of sounds are defined: initialize, begin, end, and alarm.
Currently, only FAHREN makes the initialize noise when it starts.  The begin
sound denotes the beginning of an observation, the end sound when the
observation ends, and the alarm sound when an error condition severe enough to
abort an observation (if any) occurs. 

    The Error Log program implements the sounds by sending a message to a
sound daemon on Jever.  The sounds it uses are defined by a file,
[SMT.ERROR]SOUNDS.LIS, which contains lines giving the sound Kind followed
by the sound Name, one per line.

initial		gong
begin	        train
end             doorbell
alarm           alarm
    
    If you don't like the sounds, simply edit this file.  (A backup copy of
the original version is in SOUNDS.SAV.)  To make ERROR notice a new file, type
a CTRL-C in its window.  If no sound name is given for a sound kind, that
sound kind will no longer make any noise.  There are lots of possible sound
names on file.  Or you could make/fetch your own.  (Put it in a file named
<name>.au in /home/smtobs/cactus/tone/sounds.)

    A couple of aliases have been defined for the smtobs account for this 
sound system:

	    setvol <n>

where <n> is a number between 0 and 100 sets the volume level of the noises
(and rings the cowbell so you can hear how loud <n> is).  To discover what
the above sound Names sound like, type

	    sock SOUND

followed by one or more of the above names, one per line.  (CTRL-C quits the
sock program.)
