Plugin Stops Working

Chad - Thanks for making this plugin. The bridge connects and works however the input selection in homekit stops working on occasion but seems to come back. However the bigger issue is the logs show "Unkown data response string" intermittently. Sometimes it can recover from it, other times when I receive multiple errors it become unresponsive and a reboot of homebridge is required. Any suggestions?

I'm using the default RS-232 settings, I'm not sure if there could be an issue there.
