Adding a modem manually
To add the configuration information for a modem,
in the Modem Manager:
You can enter a third-party serial device name for your serial port once that device has been configured into your system; see your serial device documentation for installation and configuration information.
To change the speed or interrupt trigger level, or to enable or disable a login on a port, follow the instructions in ``Configuring a serial port''.
Select Off if you want to prevent your system accepting incoming calls.
