Configuring the Serial Console Port as a PPP Console
You can reconfigure the console serial port as a PPP Console to support a dial-in PPP
connection using a modem.
Note: The lack of an IP address for the PPP serial interface causes the switch to
immediately return to sending the modem configuration string. Typing TTY
will re-access the CLI login prompt.
To configure the console serial port as a PPP console:
1. In the System Configuration section of the Web Agent window, select Console
Configuration. The Console Configuration dialog box opens.
2. Click PPP for your console type and click Select. The Console Port Configuration
dialog box opens.
3. Use Table 3-17 to change your console port settings.
Note: The only parameters you can change as a PPP console is baud rate and
flow control. The flow control settings are limited to None or Xon/Xoff.
