2  * Compact Disc Control Utility by Serge V. Vakulenko <vak@cronyx.ru>.
3  * Based on the non-X based CD player by Jean-Marc Zucconi and
6  * Fixed and further modified on 5-Sep-1995 by Jukka Ukkonen <jau@funet.fi>.
8  * 11-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
11  * 18-Sep-1995: Jukka A. Ukkonen <jau@funet.fi>
16  * 11-Oct-1995: Serge V.Vakulenko <vak@cronyx.ru>
20  * 13-Dec-1999: Knut A. Syed <kas@kas.no>
21  * 		Volume-command modified.  If used with only one
23  * 		parameters it will print volume-info.
26  * 27-Jun-2008  Pietro Cerutti <gahr@FreeBSD.org>
27  * 		Further enhancement to volume. Values not in range 0-255
29  * 		the uchar storing the volume (256 -> 0, -20 -> 236, ...).
