PN 88300150
Note: The Escape Code for Remote Configuration (see Appendix K) has %%%AT<CR> for the factory
default setting.
O Exiting Command Mode, Going Back On-Line
To bring the MT2834MR out of Command mode back into On-Line mode, type ATO (where
O is the letter O, not the number 0). In this case, the O command reverses what was done by
typing the Escape Code. The O command places the modem in the same On-Line mode
(Originate or Answer) that it was in prior to going into Command mode.
A Forcing Answer Mode
With the A command you can force the MT2834MR into the Answer mode. Type ATA Mode
when in Command mode to immediately bring your modem off-hook, out of Command mode
and into the On-Line Answer mode, and cause it to transmit its carrier signal over the phone
line. If no responding carrier tone is received by your modem within 45 seconds (or some
other time as determined by S-Register S7), your modem will cease transmitting its tone,
hang up, and go back into Command mode.
I Inquiry for Product Code
Some systems or software packages automatically check the "Identification" of the modem
with which they are communicating, by using the I command. This "read" command lets the
software determine the type of modem with which it is communicating.
When ATI or ATI0 is typed, the MT2834MR responds with 247. When ATI1 is typed, the
modem responds with a three-digit firmware version number.
L5, L7 Listing Current Operating Parameters
The L5 and L7 commands allow you to list the current operating parameters of your modem.
This information can be very useful when reconfiguring your modem, such as when you are
changing communications software or when you are changing your factory default settings.
To list the MT2834MR's current operating parameters, type ATL5 for the basic parameters.
Type ATL7 to list additional parameters. The parameters for all of the configuration
commands (covered in section 5.9) are listed.
L6 Listing S-Register Values
The L6 command lists the current values stored in the modem's S-Registers. This information
can be very useful if you wish to change S-Register values. (Refer to Chapter 4 for more
information on S-Registers.)
L8 Listing On-Line Diagnostics
The L8 command displays the current on-line status (e.g., Link Type, Line Speed, Serial
Speed, Type of Error Correction/Data Compression, Number of past Retrains, etc.) of the
MT2834MR, the DSP code version number, and the processor speed. This display can be
printed and used as a modem status report or as diagnostic information (such as when
calling Tech Support). This report is given only when on-line. To activate this command type
+++AT<CR> (on-line escape command while maintaining command mode), then type ATL8.
