I have some devices with an RS232-connection (e.g. a beamer, a TTL-to-RS232-adapter for my NanoPI R1 described here, etc). No i have found a RS232 to VGA adapter:
Now i wonder, if I would have this adapter-cable and would connect it to my NanoPI and plugin the right-plug in a VGA-monitor: What would I actually see? Would I really see the screen of the NanoPI (or the screen-output of whatever device which is connected)?
