Port
The port number is the port the server (listener) is accepting connections on. In most operating systems there is a SERVICES file which denotes all standard ports. If you are developing a test application (both server and client) you should use ports above 1024. In reality, you should use ports above 65000 to avoid conflict with other products who have registered their ports already.
WantsBLOCKING
DXSock support both Blocking and Non-Blocking socket calls. A blocking call will not return control to your application until the socket layer has performed the requested task. This includes routines which under some operating systems can take up to 2 minutes to timeout. In non-blocking mode, the call to the socket layer is returned immediately. This allows DXSock to evaluate the return code, and if possible retry the command automatically based upon best practice. Another difference to note is non-blocking calls use a little more CPU time than non-blocking calls.
UseNAGLE
Enables or Disables the use of Nagle.
UseUDP
