     cdcontrol -- compact disc control utility

     cdcontrol [-sv] [-f device] [command ...]

     The cdcontrol utility is a	program	to control audio features of a CD
     drive.  The device	is a name such as cd0 or acd0.

     If	no command is given, then cdcontrol enters an interactive mode,	read-
     ing commands from the standard input.

     The following options are available:

     -s	     Silent mode.  Do not print	table headers and human	readable com-

     -v	     Verbose mode.  Print as much information as possible.

     -f	device
	     Specify a device, such as /dev/cd0	or acd0.  Both absolute	path
	     and relative to /dev filename are possible.  The -f option	over-
	     rides CDROM.  If neither CDROM nor	the -f option is specified,
	     cdcontrol tries opening first /dev/cdrom, then /dev/cd0, and fi-
	     nally /dev/acd0.
