// $Revision: 1.8 $
//
// DESCRIPTION: defines hardware dependant values for the console server products
//
//
// $Log: cs_hardware.h,v $
// Revision 1.8  2004/03/24 14:49:15  billf
// added a new sentinel card type e_fiber - for the fiber NIC interface (used by cardd)
//
// Revision 1.7  2003/09/16 16:30:05  billf
// modem reset bit changed to lsb (0x01)
//
// Revision 1.6  2003/09/15 17:16:39  billf
// modem reset address changed to 1Ah,
// console & modem ID changed to 2 & 1
//
// Revision 1.5  2003/09/10 18:28:57  billf
// added a test IS_SENTINEL_MODEM_INSTALLED
// returns TRUE if the modem is installed
//
// Revision 1.4  2003/09/08 20:07:57  billf
// added constant for the board type address and the modem reset bit
//
// Revision 1.3  2003/07/17 14:16:26  billf
// renamed power_1 and power_2 to power_right and power_left
//
// Revision 1.2  2003/07/09 16:31:35  billf
// added POWER_ON_SETTING, defined as ~0
// used when initializing power status
//
// Revision 1.1.1.1  2003/03/17 15:27:03  billf
// Initial import
