PORTABLE USB MODEM

5.3.1CHANGING THE SETUP PASSWORD

1.Open a data communications program such as HyperTerminal.

2.In the terminal window, type AT#Sblackbox (or AT#Syyyyyy if you have replaced the blackbox 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 stands for 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.

4.The new password is saved automatically. You can now either 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.

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.

5.3.2CHANGING 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

(%). Setting S9 to 0 (zero) disables remote configuration entirely—but if you do this remotely, you won’t be able to change it back remotely!

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

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

3.Save the new value by typing AT&W and pressing ENTER.

4.Type ATO<CR> to exit remote configuration.
