title: writing signals to serial port
body: <p>I am trying to write data to a DMX receiver via USB to RS485 cable. I can see the correct data frames, but for the packet to follow the DMX protocol, I need a break and MAB signal. So my question is, is there a way to generate such signals? My thoughts were to write hi and lo signals with delays to the serial port but I have not found a way to do this in VS C#.</p>
