* $Log: hci.c,v $
* Revision 1.7 2004-04-20 20:42:21 schwitrs
* moved all direct asm calls from sci.c and hci.c to direct.c
*
* Revision 1.6 2002/11/24 19:46:25 schwitrs
* added optional support for kernel hardware interface
*
* Revision 1.5 2002/01/30 18:31:37 schwitrs
* cleanup
*
* Revision 1.4 2002/01/29 01:13:26 schwitrs
* removed segfault signal hack
* replaced with extra element on stack hack
*
* Revision 1.3 2002/01/23 19:47:53 schwitrs
* HciFunction: now set all SSM registers
* involves major hack to get around segfault in asm: catch signal and restart.
*
* Revision 1.2 2001/05/14 16:39:51 schwitrs
* redid HciGetMachineID- stuff from Jonathan's kernel module
*
* Revision 1.1 2000/02/03 02:49:03 schwitrs
* Initial revision
*
* Revision 1.2 1999/08/15 10:43:28 jab
* removed the HciGet and HciSet and replaced with HciFunction
