made prior to making any other setting. This procedure is located in the Utility
Modem Type menu.
3. Menus or commands that are specific to certain modem configurations are only
accessible after selecting the appropriate modem configuration. This prevents
incompatible parameters from accidentally being selected.
4. All of the windows are accessible in the Custom mode. Take caution not to select
incompatible parameters, as the modem does not shut out incompatible command
choices in the Custom mode.
