Powershell List Serial Ports + description

Question

I'd like to create a list of COM port on my computer (COM port + description). My point is to create a COM port list in order to communicate with a switch using an USB/RS232 converter.

What I try so far :

Get-WMIObject Win32_SerialPort | Select-Object DeviceID,Description

But all the COM port does not appear (example: COM11 is missing)

another attempt :

[System.IO.Ports.SerialPort]::getportnames()

here the port I need is present but the description is missing. (example : COM11 is present but with no details)

Answer 1

The above answers seem to be for deprecated Powershell objects.

I was able to use this:

Get-CimInstance -Class Win32_SerialPort | Select-Object Name, Description, DeviceID

Remove | Select-Object Name, Description, DevideID to inspect additional properties.

Answer 2

did this:

https://www.google.com/search?q=powershell+get+available+com+ports&gws_rd=ssl

found this:

http://empegbbs.com/ubbthreads.php/topics/362862/Windows_command_to_quickly_lis

which led to this:

https://github.com/todbot/usbSearch/blob/master/listComPorts.vbs

so i adapted it to this:

Get-WmiObject Win32_PnPEntity -Filter "Name LIKE 'com%'" | Where Name -match 'COM\d+'

or this

Get-WmiObject -Query 'SELECT Name, Description from Win32_PnPEntity WHERE Name LIKE "com%"'

How about this?

$c1 = new-object System.IO.Ports.SerialPort com1
$c1
BaseStream             :
BaudRate               : 9600
BreakState             :
BytesToWrite           :
BytesToRead            :
CDHolding              :
CtsHolding             :
DataBits               : 8
DiscardNull            : False
DsrHolding             :
DtrEnable              : False
Encoding               : System.Text.ASCIIEncoding
Handshake              : None
IsOpen                 : False
NewLine                :

Parity                 : None
ParityReplace          : 63
PortName               : com1
ReadBufferSize         : 4096
ReadTimeout            : -1
ReceivedBytesThreshold : 1
RtsEnable              : False
StopBits               : One
WriteBufferSize        : 2048
WriteTimeout           : -1
Site                   :
Container              :

You could do this for each port that comes back from getportnames(). You'll probably want to call the Dispose() method on each port and set $c1 to $null after you finish gathering info for it.
