3.4 Typical Modem Configuration Example

3.4.1 Managing Modem through Modem Script

I. Configuring a modem adaptation baud rate
1) Network requirements
On the router, interface serial0/0/0 is connected to a modem. It uses the standard AT
command to negotiate a modem baud rate. The interface sends the AT command to the
modem. If an "OK" is received from the modem, it indicates that the modem can
automatically adapt to the corresponding baud rate. Then, write the configuration into
the modem for conservation, and the corresponding AT command is "AT&W".
