 *
 * 03/30/04 Andy Cress - created
 * 04/08/04 Andy Cress - display response data, changed usage order
 * 05/05/04 Andy Cress - call ipmi_close before exit
 * 11/01/04 Andy Cress - add -N / -R for remote nodes   
 * 12/08/04 Andy Cress v1.5 changed usage order, moved bus to first byte,
 *                       gives better compatibility with ipmicmd.exe.
 * 04/13/06 Andy Cress v1.6 fixed istart for -U -R
