8. AT Commands

As an alternative to the web page configuration, you can configure the SBL2e over a serial port
using an AT command format. The configuration sequence is:
1. Enter command mode
2. Send configuration change commands
3. Save changes and exit
The AT command operation is different for configuration commands versus GPIO pin
programming commands. Please refer to "GPIO Server and Analog to Digital Readback" later in
this section for additional details.
