OS X serial connection, check permissions on /dev/cu.Bluetooth-Modem

[smplman]

I'm trying to run this in OS X and noticed that the server.js script loops over all of the available serial connections. This happens before the web server even gets up and running. On OS X it chokes on the bluetooth devices. I can edit the loop index to start at what ever the USB tty is running on and the script loads fine. I think there just needs to be some error catching when trying to initialize each serial connection. I have been looking into fixing this issue but wanted to make note of it here.

Error: Cannot open /dev/cu.Bluetooth-Modem

That's an OSX typical problem. cu.Bluetooth-Incoming-Port & cu.Bluetooth-Modem should be dropped from port enumeration list to allow port autodetect to work.

It could be a good idead to add a config.serialPort = "/dev/xxxx" in config.js, to force port name and passthru port detection.

This was fixed in 2016.
