-Ih    By  default, the library will use DISPLAY-HINT information when
       assigning values. This flag disables this behaviour. The result
       is that instead of
         snmpset localhost HOST-RESOURCES-MIB::hrSystemDate.0 = 2002-12-10,2:4:6.8
       you will have to write
         snmpset localhost HOST-RESOURCES-MIB::hrSystemData.0 x "07 D2 0C 0A 02 04 06 08"
