4. Whenyoufinishconfiguring the remote modem, savethe new configuration bytyping AT&W0,

press the Enter key. Then type ATO, followed by pressing the Enter key to exit remote

configuration. You can then break the connection in the normal way.

Setup

Multi-Tech modems ship with a default setup password (MTSMODEM). For security measures, you should

change the password. For additional security, also change the remote configuration escape character.

ChangingtheSetup Password

Caution: You can only change the setup password locally; you cannot do it remotely.

1. Opena datacommunicationsprogram such as HyperTerminal.

2. In the terminal window, type AT#SMTSMODEM (or AT#Syyyyyy if you have replaced the

MTSMODEM password with yyyyyy) and press Enter. The modem responds with OK if the

setup password is correct and ERROR if it is wrong.

3. To change the password, type AT#S=yyyyyy, where yyyyyy is the password, and press

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 enter more AT commands or exit the data

communications program. The next time you remotely configure the modem you must use the new

setup password.

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 more information on ASCII codes, refer to Appendix C.

1. Establish a remote configuration link with the remote modem as described in Basic Procedure

on the previous page.

2. Type ATS9=n, where n is the ASCII code for the new remote configuration escape character.

Then press ENTER.

Caution: Setting S9 to 0 (zero) disables remote configuration entirely—if you disable remote

configuration you will no longer be able to configure this device from a remote location!

3. To save the new value, type AT&W and press Enter.

4. Type ATO, then Enter to exit remote configuration.
