RESULT CODE NOTES:

*   V0 and V1 are the modem commands that determine whether the modem is to
    render numeric (V0) or verbal (V1) result codes.

*   The Q command determines whether or not results are sent.  Q0 turns on
    the result codes and Q1 turns off the result codes.

*   The default value of V and Q commands is fixed by DIP switches.  For
    example, when DIP Switch 7 is set to ON, these result codes do not
    appear on the screen unless you enter Q0 from the keyboard.

*   Another command related to the result code is the X command.  Depending
    on the selected value of this command, the result code that appears
    will vary.

*   RING only indicates that the phone is ringing.  The modem does not
    answer unless it is commanded to or unless auto-answer is enabled.

*   NO CARRIER is displayed if the carrier signal from the other modem is
    not detected for a sufficient length of time.  NO CARRIER means that
    a data call was not successfully completed, or that the carrier was
    lost during a connection.
