8 Solving Problems.
MultiModemII User Guide 76 Introduction Your modem was thoroughly tested at the factory before it was shipped. If you are unable to make a successful connection, or if you experience data loss or garbled characters during your connection, it is possible that the modem is defective.
8 Solving Problems 77 The Modem Does Not Respond to Commands Make sure the modem is plugged in and turned on.
