TeraTerm (or your terminal program of choice) and issue the commands to connect to
AWS IoT. We will be using the Skywire Development Kit in this example.
Before issuing the following commands, make sure to power cycle the modem to
ensure that the certificates are properly stored. After connecting to the Skywire modem
through TeraTerm, issue the following sequence of AT commands:
