     ASCII Log Control, [[LogFunction],[Log]

  Description:
    This command performs various functions associated with the ASCII Log.  THe ASCII Log
    is used to capture ASCII data transfered to the host over the Serial Port Interface.

  Input Parameters:

    0 - Select ASCII Log Function.
    
        This parameter selects the following ASCII log functions.
    
           0x09 - Append data to end of ASCII Log.
    
                  If Parameter 0 is equal to 9, ASCII data entered from the serial port
                  will be appended to the end of the ASCII log.  Entering a carriage return
                  terminates the ASCII data to be appended.
    
           0x0A - Enable ASCII Logging.
    
                  If Parameter 0 is equal to 0xA, ASCII Logging will be enabled.  When
                  enabled, ASCII Logging will capture all data transfered to the host
                  over the serial port interface to the ASCII Log.
    
           0x0B - Disable ASCII Logging.
    
                  If Parameter 0 is equal to 0xB, ASCII Logging will be disabled.
    
           0x0C - Save ASCII Log.
    
                  If Parameter 0 is equal to 0xC, the ASCII Log will be copied to the log
                  specified by Parameter 1.
    
           0x0D - Display ASCII Log.
    
                  If Parameter 0 is equal to 0xD, the ASCII Log will be displayed.
    
          Type:    Unsigned 8-bit value
    
          Range:   0 to 0xFF
    
          Default: None
    
    1 - Log Number.
    
        If Parameter 0 is equal to 0xC, this parameter specifies the number of the log
        to which the ASCII Log is to be copied.  If Parameter 0 is not equal to 0xC, this
        parameter will not be used.
    
          Type:    Unsigned 16-bit value
    
          Range:   0 to 0xFFFF
    
          Default: None
    
  Output Data:

    If an error occurred, the following information will be displayed.
    
          "DiagError aaaaaaaa"
    
       where
    
          aaaaaaaa is the Diagnostic Error Code
    

    If no error occurred and the contents of an ASCII Log are selected to be displayed,
    
          "Log c Entries d"
    
          (Followed by the ASCII data contained in log)
    
       where
    
          c is the log number
    
          d is the number of valid ASCII characters contained in the log
