bthset -- Bluetooth Headset utility SYNOPSIS
bthset [-v] [-c command] [-m mixer] [-p file] [-s channel] bthset [-h] DESCRIPTION
The bthset utility is used to access a Bluetooth Headset with the btsco(4) audio device. It opens the mixer(4) device and creates the con- trol connection to the headset, then conducts volume settings each way. When bthset receives a SIGUSR1 signal, it will start sending RING codes to the headset until the headset button is pressed or a SIGUSR2 signal is received. If the headset is ringing and bthset receives a button press notification, the specified command (if any) is executed. When the server channel is specified with the -s option, instead of opening the control connection, bthset will listen on the channel for incoming connections from the Headset and register as Headset Audio Gateway with the local SDP server. The options are as follows: -c command Specify an optional command to be executed when the headset responds to ringing with a button press event. This defaults to the con- tents of the BTHSET_COMMAND environment variable, if set. -h Print usage message. -m mixer Specify the path to the mixer device. This defaults to the contents of the BTHSET_MIXER environment variable, or /dev/mixer if not set. -p file Write the PID to file so that other programs can find us later. This defaults to the contents of the BTHSET_PIDFILE environment variable, if set. -s channel Register with the local SDP server as a Headset Audio Gateway and listen for connections on the given RFCOMM server channel. -v Be verbose. EXIT STATUS
The bthset utility exits 0 on success, and >0 if an error occurs. FILES

mixerctl - audio mixer control command line application SYNOPSIS
/usr/sbin/mixerctl [-a | -d dev] [-iv] [-e | -o] DESCRIPTION
Some audio devices support the audio mixer functionality. See mixer(7I) for a complete description of the audio mixer. The mixerctl command is used to control the mode of the audio mixer and to get information about the audio mixer and the audio device. See audio(7I) for details. OPTIONS
The following options are supported. If none are specified, option -i is assumed: -a The command applies to all audio devices. -d dev The dev argument specifies an alternate audio control device for the command to use. -e Enables the audio mixer function if the audio device supports it. If supported, the audio mixer may be enabled at any time. The command silently ignores the enable option if the audio mixer is already enabled. -i Prints the audio device type information for the device and indicates whether the audio device uses the audio mixer. If the device does use the audio mixer, this option displays the audio mixer's mode. -o Turns off the audio mixer function if the audio device supports it. If supported, the audio mixer may be turned off if only one process has the device opened with the O_RDWR flag, or, if two different processes have the device opened, one with the O_RDONLY flag and the other with the O_WRONLY flag. (See open(2).) The command silently ignores the disable option if the audio mixer function is already disabled. -v Verbose mode. Prints the audio_info_t structure for the device, along with the device type information. This option implies the -i option. ENVIRONMENT VARIABLES
AUDIODEV If the -d and -a options are not specified, the AUDIODEV environment variable is consulted. If set, AUDIODEV will contain the full path name of the user's default audio device. The default audio device will be converted into a control device, and then used. If the AUDIODEV variable is not set, /dev/audioctl is used. FILES
