The modem sends a string of information text to the DTE consisting of supported options
in response to the following command:
+ITF=?
The response is:
+ITF: (list of supported values),(list of supported values),(list of
supported values)
Example:
+ITF=?

3.2.9 Diagnostic Commands
#UD – Last Call Status Report
#UD is an action command requesting reporting of logged operation events. It does not
take parameters and must be the last command in the command line.
The modem logs aspects of their operation for each call, and saves these results until
cleared by one of the following events:
1. Power off.
2. Hard reset (e.g., negate DTR with &D3 set; reset button).
3. Soft reset = ATZ or AT&F.
4. ATD command issued.
5. ATA command issued.
6. Automatic answer (e.g., set register S0>0 and ring detected).
These results are NOT cleared by changing DTR, V.24 circuit 108.2, if &D0, &D1 or
&D2.
