Response Format
Description:
The Set Response Format command is used to define what manner the modem returns when commands
are sent to it. Responses can be defined to be either plain text messages or a single numeric digit.
Numeric control is better suited for machine applications while plain text is better for interpretation by
humans.

Validity:
Changes to the Response Format setting are valid during program or AT command modes. Changes
made while not in program mode will be lost upon power down. Changes made and saved while in
program mode will be retained by the modem.
Other Considerations:
Some machine applications use the plain text response as it saves reformatting the information for
presentation to a human operator.
