Use Python to access serial ports

You can use the Python serial module to access serial ports on your IX20 device that are configured to
be in Application mode. See
Application mode.
To use Python to access serial ports:
1. Log into the IX20 command line as a user with shell access.
Depending on your device configuration, you may be presented with an Access selection
menu. Type shell to access the device shell.
2. Determine the path to the serial port:
# ls /dev/serial/
by-id
#
3. At the shell prompt, use the python command with no parameters to enter an interactive
Python session:
