DropList install option with list of com ports
Is it possible to have an install option of type DropList with the ListItems being a list of com ports available on the target machine?

Found a solution getting values from registry:

Function GetComPorts
        StrCpy $0 0
getNextReg:
        EnumRegValue $1 HKLM "HARDWARE\DEVICEMAP\SERIALCOMM" $0
        StrCmp $1 "" gotRegs
        ReadRegStr $2 HKLM "HARDWARE\DEVICEMAP\SERIALCOMM" $1
        StrCmp $0 0 create
        StrCpy $3 "$2|$3"
        goto appended

create:
        StrCpy $3 $2
        
appended:
        IntOp $0 $0 + 1
        goto getNextReg
        
gotRegs:        
        !insertmacro MUI_INSTALLOPTIONS_WRITE "ComSelectionPage.ini" "Field 1" "ListItems" $3
FunctionEnd
