[Solved] Uncaught SyntaxError: Unexpected token ) [closed]

Ithink you just forgot the { } for the last function:

function getSerialOverride() {
    xdl_read_config(
        "xdl_serialports_onboard_override",
        function(response){processSerialOverrideResponse(response);},
        function(xhr, status, error){}
    );
}
