List all the serial ports (available and busy) on any of windows terminals

Question

The cmd's mode command shows all the available (to be opened) serial ports, omitting the ones which are occupied by other programs. The PowerShell's command:

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

shows all the existing ports even if they have been opened by other software. However, it doesn't show the ports which have been opened internally by PS itself. For example, if I define a new port object by:

$port= new-Object System.IO.Ports.SerialPort COM3,9600,None,8,one

the mode command does not list 'COM3', indicating that the port is actually open in another program (i.e., PS). But the first PS command above still shows it as available. Somehow PS already opens the port when the object is defined but still lists them as available! Now if I open the port in PS:

$port.Open()

PS doesn't list it anymore.

What I want is to have a cmd or PS command to list all the serial ports regardless of they are being opened in a program or not.

Solution

Try this :

1. Click on a start menu
2. Go to "run"
3. in the field type CMD
4. execute this commands in this order: a) C:>powershell b) PS> Get-WMIObject Win32_SerialPort

If you are x64 so type win64.

It should work i guess.

superuser.com/questions/835848/… - 8 In the command prompt use: C:\>wmic path Win32_SerialPort OR In PowerShell: PS> Get-WMIObject Win32_SerialPort OR PS> Get-WMIObject Win32_SerialPort | Select-Object Name,DeviceID,Description Hope this helps.

@spikey_richie cmd's wmic and chgport or PS's Get-WMIObject are the options. thanks a lot.
