I am trying to send plottable data through a different port.

Different from what? The PC determines which port the Arduino is connected to. You can't make the Arduino change that.

3

Select the port in the Tools > Port menu.

I would like the "serial plotter" to listen to a different port than /dev/ttyACM0. I have a FTDI cable that gets assigned to /dev/ttyUSB0.

Start a second instance of the IDE, select a different port and open serial plotter.

Or use picocom in a terminal to look at the data, e.g.

#exit is C-a, C-x
picocom -b 38400 /dev/ttyUSB0

To get a plot of the data I log it to a csv file

script -f -c "picocom -b 38400 /dev/ttyUSB0" stuff.csv

and then open that with LibreOffice Calc to make the plot and do other stuff.

Okay, it seems that there's no direct path. It's okay, I can write a real time plotter.
