                  Sound Generator for CenCit Chat Bell
                  
         This program is provided to help you custom configure your chat 
       bell.  When running this program you may optionally change the 
       pre-programmed defaults to suit your needs.  If you want to use 
       values that differ by more than 100-200 then it is advisable to 
       change them when prompted for.  You may still get to your desired 
       values when the program is running, but it will take longer.
       
         The first prompt asks for the type of sound you want.  They are:
            1.  Bell        (An alternating high and low tone)
            
            2.  Slide Up    (A varying tone starting at the low frequency 
                            and gradually rising to the high frequency 
                            stepping [changing value] at INCR at a time). 
            
            3.  Slide Down  (A varying tone starting at the high 
                            frequency and gradually falling to the low 
                            frequency stepping [changing value] at INCR at a 
                            time).
            4.  Siren       (Does a slide up followed by a slide down) 
            
         Then you will be prompted for the following values:
            Hi          This is the high frequency limit
            Lo          This is the low frequency limit
            incr        This is the stepping value
            delay1      This is the amount of time (in milliseconds) that 
                        the sound is on.
            delay2      This is the amount of time (in milliseconds) that 
                        the sound is off just before the cycle repeats.
                        
                       
         At this point, the sound will begin playing.  To change the sound,  
         the following keystrokes are available:
            
            Up Arrow            Increases the high tone 
            Down Arrow          Decreases the high tone 
            
            Right Arrow         Increases the low tone 
            Left Arrow          Decreases the low tone 
            
            + or =              Increases the step 
            -                   Decreases the step
            
            Page Up             Increases the sound on delay 
            Page Down           Decreases the sound on delay 
            
            Home                Increases the delay between cycles
            End                 Decreases the delay between cycles
            
         When you have the desired sound, press escape and the values will 
         be printed on the screen for you.  
         
         If you run the program re-directing standard output to a file, 
         example:
           snd > ext.cit
           
           The program will generate into that file the values needed for 
           the external.cit file.  Re-directing the output will not effect 
           any of the prompts in the sound program itself.
