That's the value I want :)  I found the correct port tag for your device
and pushed to modem-manager.  Can you also do an experiment for me?  I
need to determine the aux port #.  I want to find out which ports
respond to AT commands.  Most will, one or more won't.

For each of the ones that *do* (use minicom or screen or whatever and
send "ATI" to the port), please do the following:

cd -P /sys/class/tty/ttyUSBx  (where of course X is the tty number)
pwd

and the 'pwd' will print out something like this:

/sys/devices/pci0000:00/0000:00:1d.7/usb2/2-6/2-6:1.1/tty/ttyACM0

which is what I'm interested in.

Thanks!
