4Enter the command to configure the router or view the running status of the router. Enter “?” to get help when necessary. For details of specific commands, please refer to the following chapters.

Remote Configuration The router powers on, then creates a remote configuration environment by Environment via Async connecting to the asynchronous serial ports of the router (including

Serial Port synchronous/asynchronous serial port, AUX interface, i.e., auxiliary interface, etc.) via modem dial-up. Detailed below is the description on how to establish a remote configuration environment via asynchronous serial port, with AUX interface as an example.

To establish a remote configuration environment via an asynchronous serial port of the router, pre-configure it to flow mode. For specific setting method, please refer to the Terminal Service chapter in this manual.

The modem connected to the asynchronous serial interface should be set to auto-answer mode.

1As shown in Figure 7, connect a modem to computer serial port and another modem to the routers asynchronous serial port (AUX interface in the diagram).

2Run a terminal emulator application, such as HyperTerminal of Win9X, on the computer to establish a new connection. Select the RS-232 serial port on the computer for actual connection; set the terminal communication parameters to 9600 baud rate, 8 data bits, 1 stop bit, no parity, no flow control or hardware flow control, and select the terminal emulation type as VT100, the same as the connection established via the console port.

3Before powering on the router, power on its external modem. Initialize the router via AT command, and then dial on the remote computer to establish a connection with the router, as shown in the following figure.
