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 (%). 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.
