Remote Configuration
This mode of operation allows viewing or modifying the options of a
remote modem that supports Telenetics, Motorola, or Motorola UDS
remote configuration. Remote configuration is performed using the
front panel LCD or, more commonly,
AT
commands from the local ter-
minal. Remote configuration is initiated by the local (master) modem
through a proprietary protocol, a security code, and an acknowledgment
from the remote (slave) unit to be modified. The security code is
inserted and provides protection from unauthorized entry. The modems
are shipped from the factory without a security code.
