To help with modem configuration, sample modem record configuration details are provided for the Motorola V.3600 series modem and U.S. Robotics Sportster modem.

Modem records are configured only for modems at the host end that must dial to obtain a connection to one or more remotes. Much of the information required for a dial connection resides in the modem record.

The tables below provide sample configuration details for a Motorola V.3600 Series modem and U.S. Robotics Sportster modem. A modem record must be configured to reflect the particular type of modem that is used.

Note: For commands specific to the modem you are using, refer to the manual provided with the modem.
