Modem Helper is a customer diagnostic application that can be used to test for the presence of a Dell supported modem, and the modem's hardware and driver installation, as well as the telephone line connection to the modem.
Modem Helper was designed to help evaluate the condition of your Dell modem in a Dell PC. It will attempt to return the modem to the same state, as it was when it left Dell's factory. This application also provides information about your Dell modem.
