I need to verify if "com ports" are disabled or enabled on windows servers, so i run this command in my script

"get-itemproperty -path hklm:hardware\devicemap\serialcomm" and it shows me this

PSChildName : serialcomm PSDrive : HKLM PSProvider : Microsoft.PowerShell.Core\Registry \??\Root#PORTS#0000#{86e0d1e0-8089-11d0-9ce4-08003e301f73} : COM4 \??\Root#PORTS#0001#{86e0d1e0-8089-11d0-9ce4-08003e301f73} : COM5 Winachsf0 : COM3

If the "com ports" have been disabled in device manger then the output should not show any com ports listed or paths

So if i change the command to say this

get-itemproperty -path hklm:hardware\devicemap\serialcomm | Select-Object -Property 'PSChildName','Winachsf0'

I get this @{PSChildName=serialcomm; Winachsf0=COM3}

and if i do -Property for the other paths

\??\Root#PORTS#0000#{86e0d1e0-8089-11d0-9ce4-08003e301f73}
\??\Root#PORTS#0001#{86e0d1e0-8089-11d0-9ce4-08003e301f73}

I would get the results for COM4 and COM5

But is there a way to just get the "com" info. So that if none are found then they will have been disable but if any show then they are active and it list's which ones?

Anyone how to do this?

Thank you
