MNP Command Description:

         \Cn - Set Auto-Reliable Buffer

              \C0 - Auto-Reliable buffer disabled, default.

              \C1 - Buffers 200 characters.  If the buffer fills
                    before a Reliable link is negotiated, the modem
                    will make a NORMAL connection.

              \C2 - If the ASCII code, set by the %A command, is
                    received before a Reliable link is negotiated, the
                    modem will make a NORMAL connection.

         \Jn - BPS rate adjust

              \J0 - Disable BPS Rate Adjust - The modem will NOT match
                    the serial port rate to the speed of the modem
                    connection.  (This mode is not available when
                    using the DIRECT mode.)

              \J1 - Enable BPS Rate Adjust, default - The modem WILL
                    match the serial port rate to the speed of the
                    modem connection.

         \Nn - Set Operating Mode

              \N0 - NORMAL Mode - Modem will NOT attempt an MNP
                    connection. Data buffering, flow control, and
                    fixed data rate, bps rate adjust disabled, are
                    available.

              \N1 - DIRECT Mode, default - Modem will NOT attempt an
                    MNP connection, data buffering is not provided,
                    and the data rate WILL be adjusted to match the
                    connection.

              \N2 - RELIABLE Mode - Modem WILL attempt an MNP
                    connection.  If this reliable connection fails
                    then the modem will hang-up.  If sucessful, then
                    error free data transfer can commence at this
                    point.  Data buffering, flow control, and fixed
                    data rate, bps rate adjust disabled, are
                    available.

              \N3 - AUTO-RELIABLE mode - Modem WILL attempt an MNP
                    connection.  If this reliable connection fails
                    then the modem will connect in the NORMAL mode.

         \Qn - Set serial port Flow Control

              \Q0 - Disable Flow Control, default
              \Q1 - Enable XON/XOFF
              \Q2 - Enable unidirectional CTS/RTS












              \Q3 - Enable bidirectional CTR/RTS

         \Vn - Modify Result Code Form

              \V0 - Standard Result codes, default

              \V1 - Modified REL Result codes
