Enter the following command:
auser>xmlrpc http://localhost:4242/RPC2 device.register i/1 i/1
This should return the value of the device handle or an error indication.
To see the XML generated by the client and sent to the server:
auser>export XMLRPC_TRACE_XML=1
and repeat the previous invocation of xmlrpc.
You should see both the XML transmitted to the MD for the API and that received by the client.
