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.
Remote Configuration Commands
These commands, documented in Chapter 4 of this manual, enable you to configure various Remote
Configuration parameters: #Sx, #S=x, and %%%AT.
