Why won't my PowerShell Script work

[LuisTheOne]

Hi !

Does anyone know why this doesn't work?

$port= new-Object System.IO.Ports.SerialPort COM4,9600,None,8,one
$port.Open()
while($true) {
 
$line = $port.ReadLine()

echo $line


If ($line -eq "1"){
    echo "Hello"
}


}

If it recieves a 1 it doesn't print Hello.

are you sure the com port is right? and -eq means it is equal. if it receives a one it will print hello. and thridly is it string being sent or int? if it is integer it should just be 

If ($line -eq 1){
    echo "Hello"
}

I found out there is an invisible sign if you print it as hex

the 33 is the number as hex but there is this invisible 0D.

Do you know how to remove this or just compare without it.
