            telnet.write('\x1A')
            print 'Control Z send'
            telnet.read_until('>')
            telnet.write('exit'+ '\n')
            output = telnet.read_all()
            print (output)
        except Exception as excp:
            print('Request Time out')

tried with '\n' instead of '\r' but same result.
