Check-TCPUDPClient.ps1

The output from the script below is designed to be a framework to check TCP and UDP open ports under connection. It makes use of whatever TCP and UDP Client sockets code is native to Powershell 2.0. My original conception was to create a scripted 'fuzzer' that would send non-arbitrary data to open ports to test or provoke library module loading.  Powershell's socket facilities are impressive for a scripted language. I don't know how much documentation there is for TCP/IP.  No error checking implemented.
