I have been trying to use JunOS pyEZ to provision SRX which needs serial connection for initial configuration. Using the below mentioned code throws I/O exception:
from jnpr.junos import Device
from jnpr.junos.utils.config import Config
import logging
......
logging.basicConfig(level=logging.INFO)
dev = Device(user='root', passwd='*****', mode='serial', port='COM4', gather_facts=True)
print(dev.facts)
cu = Config(dev)
cu.load('set system host-name test', format='set', ignore_warning=True)
cu.commit()
.....
Exception:
INFO:jnpr.junos.tty:TTY: connecting to TTY:COM4 ...
INFO:jnpr.junos.tty:TTY: logging in......
INFO:jnpr.junos.tty:TTY: OK.....starting NETCONF
ERROR:jnpr.junos.console:Exception occurred: login:fileno

Using open() with the above mentioned code gives the same errors. Running a similar code with SSH connection works fine. Running it in WSL gives the same errors. P.S.: Running it on Windows 10 with Python3.7
