Command Syntax
In response to this command, the modem will report one or more lines of information text
as defined below. Information text format conforms to V.250; each line is preceded by a
pair, and terminated by . (CR and LF characters may be changed
by writing new values to the contents of registers S3 and S4, respectively.)
The modem may generate a single line or multiple lines, followed by a standard OK final
result code. For example, if call setup failed, only that result is useful. Each information
text line is formatted as follows, including one or more key=value pairs:
