The Unimodem Diagnostic Command Specification is provided by Microsoft
to enable modems to exhibit consistent behavior during data session diagnos-
tics. The latest specification revision of this command can be found on the
Microsoft Web site.
Command Syntax:
AT#UD
#UD is an action command. It does not take parameters.
Although this command is intended for use after call termination, codes are
defined so that a modem can respond before the call is placed, and during a
call for live monitoring purposes.
Command Response:

modem. Each information text line is formatted as follows, including one or
more key=value pairs:

key is a hex number, described in column 1 of Table 1.
