Создаем пару виртуальных портов:

$ socat -d -d pty,rawer,echo=0 pty,rawer,echo=0
2023/10/01 03:18:39 socat[965194] N PTY is /dev/pts/16
2023/10/01 03:18:39 socat[965194] N PTY is /dev/pts/19

Запускаем писателя на другой консоли:

$ ./writer.py
Write: GET_A
Write: GET_B
Write: GET_C
Write: GET_NORESP
Write: INVALID_CMD
...

На следующей консоли за пускаем парсер:

$ ./reader.py
