Feature request for [serial]

Hi, I know the object hasn't changed in like ... forever... but I'd like to be able to clear the serial object's buffer from Max. Sometimes the buffer will fill up before I have the opportunity to process the information, leading to mismatched bytes.

While the specific problem I'm encountering to has to do with initialization (opening a patch with a serial object that already has a port assignment), and it could be easily solved by not providing an argument, i think this would still be useful functionality to add.

Thanks
