I have a USB to RS232 adapter that creates a virtual RS232 port.
It supports anything between 300 and 1000000 baud.
in vvvv I can only choose most common bauds. I want to specify the rate myself (as there is no standard in what is allowed)
I want 250000 as it happen to be the rate for DMX. No idea though if it will work but I still want to test. The receiver it a Light board to it don’t have to drive cables or fixtures.
edit hmm. is seems there is no start bit available so it might not work properly.
Maybe it could be made up of 4 bit long pulses at 1M baud. But then I would need no stop bits or else they would be in the way.
