testing usb to serial to usb using pyserial has no output

Question

I'm trying to test writing messages to serial port using pyserial and reading it again using two usb to serial adapters connected back to vack "USB-Serial --> Serial-USB" to verify it is writing to the serial port as it is meant for communication with hardware, so I have open console witch is reading all the time

import serial

port = 'COM6'
read_ser = serial.Serial(port)

while True:
  x=read_ser.read()
  print(x)

and for writing I use

import serial

port = 'COM5'
ser = serial.Serial(port)
# ser.write(str.encode('$GPRMC,081117.24,A,5042.988302,N,1058.376556,E,14.7,,230813,0.0,E*74'))
ser.write('$GPRMC,081117.24,A,5042.988302,N,1058.376556,E,14.7,,230813,0.0,E*74'.encode())

And nothing is shown in the reading console I tried both adapters and read from external serial hardware successfully.

I'm using python 3.7 on windows 10

Answer 1

I figured it out The problem was with the pin layout as I used gender changer to connect the two serial adapters using serial cable instead solved the problem.
