At the root of the device-management source tree
1. cd demotest
   make demotest
   ./demotest
2. Create another ssh session
   cd ./demotest/cmd_cleint
   make cmd_cl
   ./cmd_cl

   then it will have "CMD to send:" prompt
   You can use the following "client cmd" to test.

   Example:

   For the first time, you need to use "attach:ipaddress:port:vendorname:freq" to set the device's IP related info.
   If successful, you will get "[ipaddress:port]CMD to send:" prompt to indicate what device you attached now. 
   This attach will subscribe default 3 types events into the server.  
   You can use the following wget to check if any events subscriptions on the device.

   wget --no-check-certificate  \
   -qO- https://RFSERVERIP:8888/redfish/v1/EventService/Subscriptions/ \
   | python -m json.tool

   You can also use "unsub:add:rm:alert" to unsubscribe all 3 types of event subscriptions on the device.

   And use "QUIT" to leave test.
