Many users prefer to manage communication settings through one of the many communication packages available for configuration and dialing. These packages allow you to select parity, terminal emulation, baud rate, phone number, transfer protocols, and other options available during a communications session.
However, you may access your modem directly without the aid of a communications package, and, in those cases when you are experiencing connect problems, direct modem access may be preferable.
System references to your modem can be made as long as the system recognizes the port to which your modem is attached. On small systems, the port ordinarily used for modem access is a COM port (COM1 or COM2). In larger systems, other logical names for the physical ports are established at system initialization.
