Data Addendum
June 15, 1998
Test and Debug AT Commands (continued)
The modem may generate a single line or multiple lines, based on modem capabilities and call results, followed
by a standard OK final result code. For example, if call setup failed, only that result is useful. Each information
text line shall be formatted as follows, including one or more key=value pairs:
DIAG <token key=value [[key=value] [key=value]] ...>
DIAG 5 characters, hex: 44, 49, 41, 47, 20
< left angle bracket (less than sign), hex: 3C
token unique 32-bit hexadecimal string 2A4D3263, hex: 32, 41, 34, 44, 33, 32, 36, 33
space space character, hex 20
key single hexadecimal numeric digit, see Table 1
= equal sign, hex: 3D
value any string as defined below (Tables 1-3, etc.)
> right angle bracket (greater than sign), hex: 3E
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.
The following table 1 includes all the items listed in Microsoft's specification for the AT#UD command. Within these
items, the one that has a check mark in the "Implemented" column is implemented in this release of the modem
product. For an item that has an extra option table, please check the corresponding option table to see exactly
which option has been implemented.
