     liseconds]  [-pause  milliseconds]  [-duration milliseconds]

DESCRIPTION
     The audial program generates touch tones suitable for  dial-
     ing  a  North American telephone.  audial can also recognize
     touch tones and produce the corresponding string.

GENERAL OPTIONS
     The following options may be used in either dial or recogni-
     tion mode:

     -audio servername
             This option specifies the NCDaudio server  on  which
             the files should be played.

DIAL OPTIONS
     The following options may be used in dial mode:

     -volume 0-100
             This option specifies the volume at which  the  data
             should be played as a percentage of the maximum pos-
             sible volume.  The default is 100 percent.

     -spacing milliseconds
             This option specifies the number of milliseconds  to
             wait in between each digit.  The default is 100.

     -pause milliseconds
             This option specifies the number of milliseconds  to
             wait  whenever a comma (,) is used in a dial string.
             The default is 400.

     -duration milliseconds
             This option specifies the duration of each  tone  in
             milliseconds.  The default is 100.

DIALING STRING
     The following characters may be used in a dialing string:

     0123456789*#
             The corresponding touch tone is generated.

AUDIAL(1)                USER COMMANDS                  AUDIAL(1)



     abcd    Tones representing the 4 "function" keys often found
             on a keypad are generated.

     ,       A blank tone whose length is specified by the -pause
             option is generated.

     Any other characters are ignored.

RECOGNITION OPTIONS
     -recognize
             Enables recognition mode.  audial  will  attempt  to
             recognize touch tones from the input device and out-
             put the corresponding character.

     -microphone
             Use microphone gain levels on the audio  input  dev-
             ice.   If  a  microphone  is  plugged into the audio
             input jack, this option should be used.

     -gain 0-100
             This option specifies the  input  gain  level.   The
             default is 95.

     -time seconds
             This option specifies how long to attempt the recog-
             nition.  The default is forever.

ENVIRONMENT VARIABLES
     The following environment variables are used by audial:

     AUDIOSERVER
             This specifies the name of default audio  server  to
             contact  if  no name is explicitly given on the com-
             mand line.

     DISPLAY This specifies  the  name  of  an  X  Window  System
             display  that  should  be  assumed  to  also  have a
             corresponding NCDaudio server.
