How to read COMport data and write in the txt?

Question

I want to use pyserial to control Ubuntu OS reboot and I need to get and read the information until to the login in the txt.

I use this code:

logging.basicConfig(filename='onoff.txt',format='%(asctime)s %(message)s', datefmt='%m/%d/%Y %I:%M:%S %p')
logging.warning(ser.readline())

But the ser.readline in the txt only have the one line , I need all information in the txt.

Is it possible read all information and write in the txt file?

Thanks!!

If you just want to individually log all the lines in the file, you can do:

for line in ser:
    logging.warning(line)
