You can use a network management tool to configure the modem from anywhere in your network from
one location. You can use the modem's password and then issue AT commands to a remote
MT9234MU-CDC modem for maintenance or troubleshooting as if you were on site with the modem.
To remotely configure a modem:
Establish a data connection with a remote MT9234MU-CDC modem.
1.
Send three remote configuration escape characters followed by AT and the setup password, and
2.
press Enter.
Example: %%%ATMTSMODEM. You have four tries to enter the correct password before being
disconnected. If the password is correct, the remote modem responds with OK.
You can now send AT commands to configure the remote modem.
3.
When you have finished configuring the remote modem, save the new configuration by typing
4.
AT&W0, and pressing Enter.
Type ATO and press Enter to exit remote configuration. You can then break the connection in the
5.
normal way.
These steps are valid regardless of whether the connection is established by the local or the remote
Multi-Tech modem.
CAUTION:
If you hang up while you are in remote configuration mode, the remote modem can lock up.
Changing the Default Password and Escape Character
Multi-Tech modems are shipped with a default setup password (MTSMODEM). Because anyone who has
an owner's manual knows the default setup password, change the password and the remote
configuration escape character.
Changing the Setup Password
Open a data communications program such as HyperTerminal.
1.
To change the password, type AT#S=xxxxxxxx, where xxxxxxxx stands for the password, and press
2.
Enter. The password can include any keyboard character, and must be one to eight characters long.
The modem responds with OK.
The new password is saved automatically. You can now either enter more AT commands or exit the
3.
data communications program. The next time you remotely configure the modem you must use the
new setup password.
Note: You can only change the setup password locally; you cannot do it remotely. Also, passwords are case
sensitive. The next time you enter the password, it must be in the same case as you set it up.
Changing the Remote Escape Character
To increase security, you can change a remote modem's remote configuration escape character. The
remote configuration escape character is stored in register S9. The factory default is 37, which is the
ASCII code for the percent character (%). For ASCII code characters, refer to Appendix D.
