This test object that will not be supported in any
released product. Setting this object allows the next
RPC call return code to be specified. The POS will
specify the binary format.
Additional information:
The format of the binary data is a one
of three formats. The first format is no binary
data, which indicates the next RPC reply should not
be modified. The other two formats are described in
RFC 1057 and encoded using XDR (i.e. the value is
the data used to instead of the actual RPC reply).
The second format is when reply_stat is MSG_ACCEPTED
and accept_stat is something other than SUCCESS.
The third format is when reply_stat is MSG_DENIED.
Notice that all RPC replies that do not contain any
'results' are supported.
