Here's a simple test-port.

function Test-Port{
Param([string]$srv,$port=5001,$timeout=1000,[switch]$verbose)
$ErrorActionPreference = "SilentlyContinue"
$tcpclient = new-Object system.Net.Sockets.TcpClient
$iar = $tcpclient.BeginConnect($srv,$port,$null,$null)
$wait = $iar.AsyncWaitHandle.WaitOne($timeout,$false)
if(!$wait)
{
$tcpclient.Close()
if($verbose){Write-Host "Connection Timeout"}
Return $false
}
else
{
$error.Clear()
$tcpclient.EndConnect($iar) | out-Null
if($error[0]){if($verbose){write-host $error[0]};$failed = $true}
$tcpclient.Close()
}
if($failed){return $false}else{return $true}
}
