Sorry for not being clear, the /dev/ttyUSB3 is a debug port for uBlox
SARA EVK, I was able to use minicom to connect to /dev/ttyUSB3 and to
get all AT command response.

The permission was setting to only allow root access, so I ran both
minicom and application in sudo, "sudo ./stream", if that is a
problem, I'll change the access permision to user mode.

Thank you very much.
