When setting up the modems we scan for hardware and then send AT commands to the ports to see which responds. For one reason or another the R410, which only has 1 AT command port, seems to get tied up and does not return an OK when probing the ports.

raise SerialError('Unable to detect a usable serial port')
Exceptions.HologramError.SerialError: Unable to detect a usable serial port
Expected behavior
The modem should be properly detected
Actual behavior
Serial port is not available and prevents the modem from being able to be setup properly
Steps to reproduce the behavior
Plug in an R410 and use our SDK to try and run code with it.
System information
OS Platform and Distribution (e.g., Linux Ubuntu 16.04):
