Remote Configuration
This mode of operation allows viewing or modifying the options of a
remote modem that supports Motorola or Motorola UDS remote
configuration. Remote configuration is performed using the front panel
LCD or, more commonly,
AT
commands from the local terminal.
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.
