Use Python to access serial ports

You can use the Python serial module to access serial ports on your Connect IT 16/48 device that are
configured to be in Application mode. For example, you can configure USB ports to function serial
ports and interact programmatically with those ports. See
about configuring a serial port in Application mode, and see
about configuring USB ports on the device to function as serial ports.
To use Python to access serial ports:
1. Log into the Connect IT 16/48 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
