Python - telnet - automation APC PDU

I am attempting to automation turning off connected devices to an APC PDU using python's built in telnet functionality. I believe I am able to enter in the username and password, but I cannot proceed after that. My code is as follows:

    telnet_session = telnetlib.Telnet(host=self.apc_ip)
    self.logger.info("Entering APC Username")
    telnet_session.read_until("User Name :")
    telnet_session.write(self.apc_username + "\n")
    self.logger.info("Entering APC Password")
    telnet_session.read_until("Password  :")
    telnet_session.write(self.apc_password + "\n")
    sleep(2)
    print telnet_session.read_all()

I'm running windows so I believe that https://github.com/quackenbush/APC is not an option as I cannot install pexpect.

Any help would be appreciated.

Thanks,

The issue was I wasn't sending the correct end line.

In windows it's \r\n, not \n
