DESCRIPTION

       The  audial  program generates touch tones suitable for dialing a North American telephone.  audial can also recognize touch tones and pro-
       duce the corresponding string.

GENERAL OPTIONS

       The following options may be used in either dial or recognition mode:

       -audio servername
	       This option specifies the Network Audio System 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 possible 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.

       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 output the corresponding charac-
	       ter.

       -microphone
	       Use microphone gain levels on the audio input device.  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 recognition.  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 command line.

	       server.
