 *
 * 01/08/02 Andy Cress - created
 * 01/31/02 Andy Cress - converted to use ipmi_cmd_ia, 
 *                       added more user options
 * 02/06/02 Andy Cress - added ipmi_cmd_va
 * 02/22/02 Andy Cress - added -s to reboot to service partition
 * 07/02/02 Andy Cress v1.3 added more Usage text
 * 08/02/02 Andy Cress v1.4 moved common ipmi_cmd() code to ipmicmd.c
 * 09/24/02 Andy Cress - stubbed in OS shutdown option
 * 01/29/03 Andy Cress v1.5 added MV OpenIPMI support
 * 04/08/03 Andy Cress v1.6 added OS shutdown option (-o)
 * 05/02/03 Andy Cress v1.7 leave console redir alone in SET_BOOT_OPTIONS
 * 05/05/04 Andy Cress v1.8 call ipmi_close before exit, did WIN32 port.
 * 08/09/04 Andy Cress v1.9 make sure to show error if ccode != 0, and
 *                          detect Langley platforms to do special 
 *                          watchdog method for -o option.
 * 11/01/04 Andy Cress 1.10 add -N / -R for remote nodes   
 * 11/16/04 Andy Cress 1.11 add -U for remote username
 * 11/30/04 Andy Cress 1.12 fix bug 1075550 with -o -N, skip -o if not local.
 * 03/28/05 Andy Cress 1.13 add netapp_reset commands for platforms that
 *                          use this instead of chassis_reset.
 * 05/16/05 Andy Cress 1.14 add -u option for power up
 * 03/31/06 Andy Cress 1.15 add -e -p -m options
 * 09/18/06 Andy Cress 1.20 allow more platforms to do soft reset, and
 *                          if Tyan, ignore set boot options errors.
 * 01/10/07 Andy Cress 1.25 added reset_str(), modify initchar (6) if -o.
