VVerbose Result Codes
Selects whether the responses to modem commands use terse or verbose format. Terse responses consist only of a numeric digit followed by a carriage return (register S3), while verbose responses consist of a text message preceded and followed by a carriage return/line feed. The responses and their terse/verbose formats are shown below.
NOTE:
Result codes 5 and above must be explicitly enabled by the ATX command.
Command responses containing data are always framed by carriage return/line feed regardless of the V option selected.
