16 CHAPTER 2: 3COM ROUTER USER INTERFACE
4 Enter 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
Environment via Async
Serial Port
The router powers on, then creates a remote configuration environment by
connecting to the asynchronous serial ports of the router (including
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.
1 As 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).

2 Run 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.
3 Before 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.
