Python: read and send via serial interface from Notebook to Notebook

Question

Hi guys I would like to receive and send data via a USB interface. My idea is simple: I have two Notebooks wired by using USB. On the first notebook1, the software: "serial monitor" is running for reading the data protocol. I would like to send messages with my Python program(notebook2).

The next step i would like to recive messages from the notebook1. The reciving massages should be saved in text file by python

Example :

   (Python Program)notebook2 ----------------USB cable--------------------notebook1 (Serial Monitor for read/send) 

should send a message (ABC)                                               should recive the message (ABC)

after that the next step:

should read message (CBA)                                                 should send message (CBA)
print(_recived_message_)

Code here i got:

import serial.tools.list_ports as port_list
import serial
import time

ports = list(port_list.comports())
for p in ports:
    print (p)

    s = serial.Serial('COM6')
    res = s.read()
    print(res)

serialString = ""
while 1:

    if serialPort.in_waiting > 0:
        serialString = serialPort.readline()

        try:
            print(serialString.decode("Ascii"))
        except:
            pass

Output:

C:\Users\user\anaconda3\envs\ReadUSB\python.exe C:/Users/user/PycharmProjects/ReadUSB/main.py
COM6 - Prolific USB-to-Serial Comm Port (COM6)

i hope you guys can help me out
