   $ man snmpcmd
   
   OUTPUT OPTIONS
       -Oa    If a string-valued object definition does not
              include a Display Hint, then the library attempts
              to  determine  whether it  is an ascii or binary
              string, and displays the value accordingly.  This
              flag bypasses this check, and displays all strings
              as ASCII.  Note that this does not affect objects
              that do have a Display Hint.

       -Ox    This works similarly to ’-Oa’, but displays strings
              as Hex.


Or

        case 'a':
            netsnmp_ds_set_int(NETSNMP_DS_LIBRARY_ID,
                               NETSNMP_DS_LIB_STRING_OUTPUT_FORMAT,
                               NETSNMP_STRING_OUTPUT_ASCII);
            break;
        case 'x':
            netsnmp_ds_set_int(NETSNMP_DS_LIBRARY_ID,
                               NETSNMP_DS_LIB_STRING_OUTPUT_FORMAT,
                               NETSNMP_STRING_OUTPUT_HEX);
            break;
