Result Codes
After issuing a command, a result code will typically be displayed on the screen to inform you if the
command was successful, unsuccessful, improperly formatted, etc. When in the command mode,
thirteen possible result codes may be returned. The result codes can be set to display as either digits
or words by accessing the Verbose command, ATV. The digit code is returned when the Verbose
mode is OFF (ATV0); the word code is returned when Verbose is ON (ATV1). See table 9.2 for more
information on Verbose format.
