4YDM not responding to serial commands?
I have a 4ydm that I am trying to control (used off ebay), but for whatever reason I am unable to get it to respond to serial commands. If I run a terminal program straight off my serial port on my laptop, I get no response when I send commands. The same is true if I disconnect and reapply power. I would assume some type of data should be spit out the serial port, right?
