4.3.2 Gateway Reports
The gateway will report a Reset whenever one occurs. Most likely causes of reset are power on reset, host
commanded reset, or gateway micro watchdog error. The gateway does a cold start on all resets (all information is
lost). The gateway will also report error conditions with the Report Error message below. See section 4.3.2.1 for
error code definitions.
The gateway will also echo back all system commands.
