Notes:

1. The Read Change Flags are cleared by reading this command.

2. The Command Change Flags are cleared by reading their respective command.

3. All data is read only.

This command is intended to aid in minimizing constant polling of all commands to determine status. All

data that changes autonomously is contained within this response. The command change flags can be used

to determine if a parameter is changed by another source, for example via the front panel. It can also be

used to help create a local database of modem parameters.
