Remote configuration is a network management tool that allows you to configure the MultiModem anywhere in your
network from one location. With password-protected remote configuration, you can issue AT commands to a
remote modem for maintenance or troubleshooting as if you were on site.
Basic Procedure
The following steps are valid regardless of whether the connection is established by the local or the remote Multi-
Tech modem.
Note:
a data connection.
Setup
To Change the Setup Password
To Change 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.
