This function takes the same parameter as PEON and returns 0 if PEX is
not activated for the specified window (or Job) and returns a value not
equal to 0 if PEX is active. If no parameter is specified, then this
function just checks if PEX is active at all. If a pre-JS ROM is
installed, then this function will return the value -19.
