I've had trouble with the cheaper 2-pin Serial to USB connectors where they don't have a unique serial number, and for some reason assigning by port location forced the PI to choose only one (one of three) adapters to favor and ignore the other two. I only paid $4 for these cheap ch341 chipset adaptors, so I ditched two of them and bought a better quality Nextech serial to USB adaptor with the 5 wire pinout and TX/RX led indicators.
Are you sure? I tested this last spring, and I could have 3 or more arduinos (using ch341) assigned to different ports. It even works remembering which ports they are plugged to a hub.

How do I test out the datastreams on both the RX (IN) and TX (OUT) ports on my single send/recieve adaptor to make sure I've got connection and NMEA0183 data?Openplotter cannot control in or out, a serial port will have both. Can't you test it by seeing if it is working?
It may just be that my ch341 adapters were cheap. I haven't found anything on this forum where anyone else had a similar problem with ch341 adaptors. However I feel better using a higher quality adaptor for my autopilot anyway. I'm new to pypilot and haven't tried it out yet - that's the next step. I just want to make sure Open Plotter is reading and transmitting on my adaptor first which is a feature that seems to have been available on previous verisons of Open Plotter but not with this realease due ot the absence of the "BOTH" serial connection.
