I have a little kingdel box that has 5 actual, 9 pin serial ports. I am working with arduino and need my active usb port to show up as a com port, but it doesn't. ls /dev/tty* does not list any usb devices. Is there a way to make the usb port a com port in this case? Ubuntu 18.04.3 LTS Raymond Norton LCTN 952.955.7766 -------------- next part -------------- An HTML attachment was scrubbed...
