Debug Serial Usage
The nRF9160 Feather comes with an on-board Silicon Labs CP2102 USB-to-UART chip. You can use it with most serial terminal viewers. If you have an older version of Windows you will have to install the driver. The download is located here.
Here's some recommendations for software to communicate with the nRF9160 Feather. No matter what program you use, the standard baud rate for the console is 115200. All other options are standard/default (8 bits, oon-pairty, 1 stop bit).
zephyr-tools-monitor comes with the Zephyr Tools VSCode Plugin. Here is the help dialog:

nRF Connect For Desktop - LTE Link Monitor
If you haven't already, make sure you check out the LTE Link Monitor. It's a great multi-purpose tool for using and debugging the nRF9160 Feather.
CoolTerm has been my go-to for testing and debugging. Fortunately it's also multi-platform! You can download it by going here: https://www.freeware.the-meiers.org
