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 ASCII code characters, refer to Appendix E. 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.
To save the new value, type AT&W and press Enter.
4.
Type ATO<CR> to exit remote configuration.
