NOTES:

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

*   The Q command determines whether or not results are sent.  

*   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.
