PowerShell cmdlets Test-netConnection

I used to use telnet client when i needed to check if determined port was open, but in Windows telnet client is not installed by default, in Windows 2012 R2 we have a cmdlets test-netconnection, this cmdlest can verify if determined is open, below an example:

If TcpTestSucceeded is true the port is open, very simple and  cool cmdlets, never more telnet client in my servers.
