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 <CR><LF> pair, and terminated by <CR><LF>. (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:
Syntax #UD
Response DIAG <token key=value [[key=value] [key=value]] …>
Defined Value
DIAG 5 hexadecimal characters (44h, 49h, 41h, 47h, 20h)
< Left angle bracket (less than sign) (3Ch)
token Unique 32-bit hexadecimal string 2A4D3263(32h, 4h1, 34h, 44h, 33h,
32h, 36h, 33h)
Space space character (20h)
Key One- or two-digit hexadecimal number (see Key in Table 3-4)
= Equal sign (3Dh)
Value Any string as defined below (Table 3-4 - Table 3-9 as appropriate)
Right angle bracket (greater than sign) (3Eh)
Unless otherwise noted, all values are hexadecimal numbers. Any numeric values from
tables in ITU V.58 are converted to hexadecimal. Multi-digit values are reported MSD first.
Leading 0’s may be deleted. See examples in Table 3-13.
