port in Application mode.
To use Python to access serial ports:
1. Select a device in Remote Manager that is configured to allow shell access to the admin user,
and click Actions > Open Console. Alternatively, log into the LR54 local 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:
# python
Python 3.10.1 (default, May
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
