        <div>Pete,</div>
        <div><br>
        </div>
        <div>If you are using the same USB devices all the time and do
          not expect changes, consider doing udev rules. Below is an
          article I wrote about it. Basically it recognizes your USB
          device based on certain ID's and you can name the device
          whatever you want. As far as communicating, "expect" scripts
          is as good as any tool I can think of. The only thing that is
          probably better is Tera-Term, but that is strictly windows. It
          is quite good though and I wrote a tool to run scripts to 300
          edge routers using Tera-Term. One thing I used to do is use
          "socat" to send the serial device to a raw TCP port and
          communicate over the network. In general I do everything I can
          to not communicate to USB devices due to their constant
          connection issues. I prefer using UART if possible. </div>
