Fix Golang Code and Test

hi I am analyzing the code in github. ([login to view URL]) Some of the code's features do not work. The server and the client communicate with each other, but the client does not perform the command properly. Make sure the watchdog code is working. watchdog code should works. You have to build and run it yourself to check the problem. I will provide a windows server when we contract. And will provide the necessary things. It is easy to build. i also provides an build and run manual. should be add comment to code and add code to check the count of real-time clients
