Here's an implementation\nwith standard long-poll exception handling. This should run until interrupted and\nthen exit cleanly.\n\n```python\nfrom time import sleep\nimport watlow\n\ntc = watlow.TemperatureController('/dev/ttyUSB0')\ntry:\n    while True:\n        try:\n            print(tc.get())\n        except IOError:\n            print('disconnected')\n        sleep(1)\nexcept KeyboardInterrupt:\n    pass\nfinally:\n    tc.close()\n```\n\n\n",
