Use Python to access serial ports
You can use the Python serial module to access serial ports on your LR54 device that are configured
to be in Application mode. See Configure Application mode for information about configuring a serial
port in Application mode.
To use Python to access serial ports:

2. Determine the path to the serial port:
# ls /dev/serial/
by-id
by-path by-usb port1
#

Python session:
# python
