Info,

Yes you can use GetKeyState and check if it's least-significant bit is set or not which means, toggle or not toggled respectively.

#include <WinAPI.au3>

Global Const $VK_CAPITAL = 0x14
Global Const $VK_NUMLOCK = 0x90
Global Const $VK_SCROLL = 0x91

Global $avVKs[3] = [$VK_CAPITAL, $VK_NUMLOCK, $VK_SCROLL]
Global $avKeys[3] = ["Caps Lock", "Num Lock", "Scroll Lock"]
Global $tKeys

For $i = 1 To 2
    $tKeys = _WinAPI_GetKeyboardState()
    
    For $j = 0 To UBound($avVKs)-1
        If BitAND(1, DllStructGetData($tKeys, 1, $avVKs[$j]+1)) Then
            ConsoleWrite("+ " & $avKeys[$j] & " is toggled." & @CRLF)
        Else
            ConsoleWrite("! " & $avKeys[$j] & " is not toggled." & @CRLF)
        EndIf
    Next

    ConsoleWrite(@CRLF)
    Send("{NUMLOCK toggle}{CAPSLOCK toggle}{SCROLLLOCK toggle}")
Next



Func _WinAPI_GetKeyboardState()
    Local $tByteArray, $pByteArray
    Local $aRet
    
    $tByteArray = DllStructCreate('ubyte[256]')
    $pByteArray = DllStructGetPtr($tByteArray)
    
    $aRet = DllCall('user32.dll', 'int', 'GetKeyboardState', 'ptr', $pByteArray)
    If @error Or $aRet[0] = 0 Then Return SetError(1, 0, 0)
    Return $tByteArray
EndFunc
