Changing the Remote Escape Character
To further improve security, you can change a remote modem’s remote configuration escape character either
locally or remotely. 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.
Caution: 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, and press Enter.
3. Save the new value by typing AT&W and pressing Enter.
4. Type ATO and press Enter to exit remote configuration.
