The script reads the content of the input file, checks for lines matching "<Key> is <Value>".
The results will be stored in a hashtable until a key named "PortName" (the last element in a block) is found, and then written to the pipeline, from where they will be picked up by ConvertTo-Html and finally Set-Content.
$TxtFile = 'C:\PS\temp.txt'
$HtmlFile = 'C:\PS\temp.html'
$HtmlHead = @'
<style>
	TABLE{border-width:1px; border-style:solid; border-color:black;}
	TH{border-width:1px; padding:1px; border-style:solid; border-color:black;}
	TD{border-width:1px; padding:1px; border-style:solid; border-color:black;}
</style>
'@

$Properties = [ordered]@{}
Get-Content $TxtFile | ForEach-Object {
	If ($_ -match '\A(?<Key>\S+)\s+is\s+(?<Value>.+)\Z') {
		$Properties[$Matches['Key'].Trim()] = $Matches['Value'].Trim()
		If ($Matches['Key'] -eq 'PortName') {
			New-Object -TypeName PSObject -Property $Properties
			$Properties.Clear()
		}
	}
