You can poll a human-readable status message from FD70 using the command STATUS through the CLI. The status message contains information about:

  • Device configuration
  • Maintenance alerts
  • Hardware failure alerts
The character numbers (flags) not listed in the tables below are either reserved for future use or are defined but not implemented. These flags have a fixed value (0).
