rgbAttrBuffer [in] Contains data for the attribute to be set. Depending
on eAttr, the rgbAttrData will be mapped to the
appropriate structure as shown in the following table .

Data Structure contained in rgbAttrBuffer
ITC_READ_FILTER defines the grid structure.
BOOL
TRUE Enable scanner.
FALSE Disable scanner.
BOOL
TRUE Reader Engine controls good read LED.
FALSE Good read LED is not controlled.
BOOL
TRUE Reader Engine controls data valid LED.
FALSE Data valid LED is not controlled.
BOOL
TRUE Reader Engine issues beeps.
FALSE Beeps are not issued.
ITC_BEEP_VOLUME
An enumerator that identifies the beep volume level con-
trol. Valid range for S9C:
typedef enum tagBeepVolume
{
ITC_BEEP_VOLUME_LOW = 0,
ITC_BEEP_VOLUME_MEDIUM = 2,
ITC_BEEP_VOLUME_HIGH = 1 //Default
}ITC_BEEP_VOLUME
Note: Due to the hardware design on this 700 Series Com-
puter, the volume level can be either
OFF (ITC_BEEP_VOLUME_LOW) or
ON (ITC_BEEP_VOLUME_MEDIUM/HIGH).
DWORD
A value that identifies the tone frequency in Hz. Valid
range for S9C: 1000–4095 Hz (default: 2090).
Note: Value is divided by 10 for storage. On retrieval, the
scanner rounds off the value to the nearest 10 Hz, then mul-
tiplies the value by 10. For example, the value sent to the
scanner is 2095. On retrieval, the value returned is 2090.
