AT#UD Unimodem

Diagnostic

Command

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:

In response to this command, the modem reports information about the

modem. Each information text line is formatted as follows, including one or

more key=value pairs:

DIAG <token key = value [[key = value] [key = value]] …>

Where, token is a unique 32-bit hex number 2A4D3263

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

value is a string defined by column 2 in Table 1.

Note

Unless otherwise noted, all values are hexadecimal numbers.
