The example below shows how to use the serial_connection to obtain the name and friendly description of a defice given its serial number, without the need to establish a serial port connection.
# Import serial connection class.
from serial_connection import SerialConnection
if __name__ == "__main__":
# Get device name and friendly description, without the need
# of a serial port connection, if none is found, an exception is
# raised.
name, description = SerialConnection.get_device_info("R246744")
print(name)
print(description)
