++  * Revision 1.58  2003/02/02 18:54:22  rogerh
++  * FreeBSD changes for support of dspN.M (eg dsp0.0) sound card entries.
++  * Problem reported by Lars Eggert <larse@isi.edu>
++  *
++  * Revision 1.57  2003/01/06 19:25:07  rogerh
++  * Add NetBSD video support.
++  * Add correct includes for OSS ioctls (note the proper way to do this now
++  * is via pwlib commands)
++  * From Andreas Wrede, taken in part from NetBSD's package system
++  *
++  * Revision 1.56  2003/01/06 19:10:22  rogerh
++  * NetBSD uses /dev/audio and not /dev/dsp
++  *
+   * Revision 1.55  2002/12/12 09:03:56  rogerh
+   * On two FreeBSD machines, Read() calls from the sound card were not blocking
+   * correctly and returned with less bytes than asked for. This made OpenH323
